Where is the best place to play D&D online right now? 

Tried to play on dnd online through rolld20 a several times and was not very impressed with it. The learning curve was high. I have invested a lot into dndbeyond and dont want to double dip by buying do modules for both dnd beyond and d20. 

Just would like to get some updated information. I have seen some promo videos on youtube for rolld20 and would hope that it has gotten better.  

Thank you for you input. 

There is an extension that will allow you to use character sheets on DDB (with all your purchased content) with Roll20 called Beyond20. It's simple to install and use and works really well. It is a chrome extension, but I've tested it with Edge, Firefox and Brave and it seemed to work fine with each. While it's true that Roll20 does have a bit of a steep learning curve, I found that I picked it up pretty quickly. They have a tutorial that, while a  bit overwhelming, explains everything pretty well.

On the DM side, you are sort of out of luck with Roll20 though, as you will have to manually import any maps, etc. There is also Foundry VTT which many people seem to love, but I've not used it so I can't really speak to that. 

It really depends on what you want this "place" to provide. Most groups I know use Roll20 for the VTT and nothing else - Discord or Zoom or whatever for communication; D&D Beyond, a fillable .pdf or plain old paper for character sheets, DropBox or Google Drive or some other cloud service for sharing documents. Modules can be bought anywhere, or the DM homebrews a campaign.

If you're looking for alternative VTTs, there's a list here: https://www.dnd-compendium.com/dm-resources/virtual-tabletops. I'd also suggest checking out Owlbear Rodeo - it's fairly basic, but that also makes it really simple to use. 

The Google Chrome extension AboveVTT adds a VTT to dndbeyond.

I've only tried Roll20 and agree with the OP. The best thing it has going for it is that KaKaRo coded the Chrome extenstion for DDB. Otherwise it would be barely usable. 

I use Tabletop Simulator, it works really well for those who prefer actual battlemaps to theatre of the mind, and the community has uploaded 3D miniatures of most of the creatures in MM, VGtM and MToF. There are plenty of community created tables as well, of varying quality, but some are quite good. Complaints wise, it can take a while for a DM to get used to it, and if you have a dungeon with more than one floor it can be quite hard to run without showing the entire floor plan. It can get pretty laggy sometimes as well so may require fairly decent PC's. I really like it however.

Roll20's graphics and DM interface are not great, but at least programming a character to do exactly what I want is easier than DDB. But also Roll20 had a pretty good user intro tutorial. I've got a DM that wants to use Foundry, but I was at sea trying to use it. Are there any good tutorials out there for Foundry?

My point was that I didn't find it intuitive to use. Hence asking specifically for recommendations for tutorials that did work, and not 'go trawl through Youtube.'

Nothing's more intuitive than pen and paper, IMO. :p If all you need from a VTT is to show maps on a grid and icons for characters, go with something that doesn't try to give you more than that. Not trying to admonish anyone here, if you do want more functionality then obviously find what gives it to you in the most straightforward manner, but my old school education tells me to keep things as simple as possible. And given that I like to homebrew stuff and that stuff isn't always convenient to code on digital platforms, I know how to butter my bread best.

I think if you're coming purely from a desire to just have a place to virtually display a map while doing all the bookkeeping and such with actual pen and paper, then you could just as easily stream a digital art program like photoshop or something and just move icons around that way. Hell, you could point a webcam down at an actual tabletop board and stream it to friends.

That said, I think Roll20 is probably the most "popular" platform right now despite requiring a good amount of work to accomplish anything but the most basic of functions for the same reason that Youtube is so popular... it's the one that most people are already using, so even if something technically better comes along people tend to just stick with what they know already. "Better The Devil You Know..." and all that.

We are doing fine with roll20. Occasionally the voice chat has issues but we just reconnect and it's fine. It's true it has a learning curve but once you're over it, it's a decent system. The things you can do with lighting and line of sight are things you can't do any other way short of having all your players isolated in different rooms all getting different customized narration or visuals regarding what they can see.
