Having recently watched loads of videos about rolling up new characters (particularly Nerd Immersions shorts) and the crazy ways people do it, I've been inspired to run some oneshots using them, to see what my players enjoy. 

What do y'all use when creating characters? Is the standard 4d6 and drop the lowest your jam? Or do you prefer the whackiness of stuff like 1d12+6?

I use the standard 4d6dl.

Depending on the type on game (online, IRL, one shot, campaign) ability score generation method i use include standard array, point buy, Roll 4d6 drop lowest and 3d6. 

It depends on how much dice chaos my players want to have vs. something that ensures they are all equals (standard array, etc.).

There is a thread How do you roll stats? - Dungeon Masters Only - Dungeons & Dragons Discussion - D&D Beyond Forums - D&D Beyond (dndbeyond.com) that has collected a bunch of interesting dice rolling options.  Like one started from 2d4 +2d6 there are some other interesting ones in there too.

I myself tend towards the 4 d6 drop the lowest.

When I roll, it’s always 4d6 drop low. But I’ve always wanted to try 2d6+6. Minimum of 8, and a slightly higher average than 3d6. It seems, to my not mathematical mind, like it could work pretty well. 
I also found interesting this system (it may have been in 13th Age) when you start with a 13 in everything, and roll 6 die. You assign each one a letter, then add one and subtract one from each number, so it’s like 13+A-B, 13+B-C, and so on until the last one is 13+F-A. So every die gets both added and subtracted one time.
I don’t know how well it would work, but it seems kooky enough to be fun.

 I prefer the point buy method, but I've always wanted to try the following:

Everyone, including the DM, rolls 4d6 drop lowest for all 6 numbers, rolling 3 sets (roll more or less sets as desired). Then the players decide which set of numbers to use from all the sets and that one set is used for all of the players ability scores.

It eliminates the possibility of wild swings in PC ability scores between players and gives everyone (even the DM) a fun part in character creation.

My absolute favorite is to roll the stats in order and build the character from that, but not many people like to play that way.

If it is for a one-shot, definitely 3d6 rolled in order.

For anything more serious, points buy.

If it's a campaign run in my family, I'll have the fun of 4d6 drop lowest for the randomness and variety.

If I'm playing with strangers (Eg at the FLGS) I always do point-buy. I get paranoid that they'll think I'm cheating if I roll high and don't like the idea of only being able to roll low or medium without the opportunity for high. So instead, I go point-buy so I can show that I'm playing by the rules. Never had an issue...just one of those things that's in my head.

I've also used other rolling methods in the past such as

4d6 drop lowest in order

3d6 reroll 1's 

3d6 x 7 times keep best 6 rolls.

6d3

5d4

6 + 2d6

When I DM, I give players the option of either point buy or 4d6dl, but with a few rules regarding re-rolls if you fall under or over certain thresholds.  Those thresholds are a fairly wide range—designed to ensure a character is functional, but does not eclipse those who prefer to use point buy—while still allowing there to be risk and reward to rolling the dice.

As a player, I’ll do whatever my DM tells me, even if it is (ick) Standard Array. 

I prefer 4d6, drop the lowest, reroll any 1s until you get something higher than 1, and reroll if you don't have at least two ability scores at 14+.  It's worked well for me so far.

I think the method I want to try someday is everyone in the group rolls 4d6, drop lowest, reroll 1s always. Then everyone votes for the best set and the one with the most votes is the one everyone gets, assigning the scores how they like. You get the randomness of rolling but the equality of point buy. Anyone else tried that, if so how did it go?

I think even with each member rolling 4d6 minus lowest should give at least one really useful option.  Rerolling 1s should give you more heroic stats.

Alternate version of this: between the players and the DM, you roll six set of stats using 4d6 drop lowest

You then lay the six sets out in a 6x6 grid

Each player then selects a set of stats to use from a row, column or diagonal

4d6 reroll 1's.

Players are the hero's of the world, should be superstars. 

Our group uses standard point buy. Rolling is just a recipe for making one player miserable as their character is useless. I do wish starting scores could go below 8 though (down to 6). As having an 8 doesn't feel like an actual interesting flaw. It just feels like something you're not amazing at.

I don't like all these rolling options or high point buys where you're guaranteed amazing scores. I like DnD being a 'zero to hero' story. Not a bunch of demigods at level 1.

I have got a one shot set up where it's a 15 point buy, with max score being 13 and min score being 6 (before species bonuses). Players are level 0 and start with 4 characters each.

When I do rolls, I do 4d6dl where the players get to choose any array rolled by the group. Obviously this is to avoid power imbalance and a nice side effect is that it increases the chance of interesting arrays, since 4d6dl often ends up with "boring" stats (all 12, 13, 14).

I find most of the whacky opinions for getting "good" arrays to be quasi-random detours to what could have been point-buy with extra points.

In any case, I usually use point-buy or standard array anyway. Mechanical disadvantage through a low stat does not make an interesting character, but good flaws that are played well do. High stats also tend to make characters weaker in play, though players are often tricked by nice high numbers. A properly DMed game will have challenges adjusting for character strength, and because PC defense won't scale as much as PC offense through high starting stats, using higher CR will lead to more deadly low level encounters.

Have them roll munchkin, 24d6 and drop the lowest 6.  All stats have to be assigned from highest 3, to next highest 3 and so on.  It can get entertaining to see like the following:

18,15,12,12,9,7

Good chance at higher stats, I just tell the players if they roll this, there will be no upping the scores, you get what you get.  If you get a bad roll you got a bad roll because its fairly rare with this method.  They are almost always guaranteed one 18.
