The Artificer can cast 7th level spells more times than the wizard.

"Each item you create must be based on a different plan you know."

So you can't make a spare helm of teleportation. And the title of "can cast 7th level spells more times than a wizard" is also inaccurate. can cast teleport more times I totally concur.

This is fascinating, but I think I'd rather go for the spellcasting ability of a Wizard.

Of course, a wizard of that level can also make a Helm of Teleportation... and other magic items, including pretty much anything an artificer can make... so a comparison that uses magic items to achieve, isn't really accurate since the wizard could just do the same thing to come out on top again.

 An artificer can make a helm of teleportation at 14th level in a day with replicate magic item.  A wizard can make a helm of teleportation in 50 days for 2000 gp that has 3 charges.  The artificer replicated helm of teleportation also starts with 3 charges but the artificer can recharge that helm of teleportation using low level spells with the magic item tinker abilities gained at 6th level to out teleport that same wizard many, many times at such a lower investment to make said item.

Being able to cast teleport with a 1st level spell slot easily surpassed that wizard example.

Artificers can use and recharge a cube of force too that way.  

The wizard does not necessarily come out on top.  The trick is in finding items on the magic plans list that use charges so that the artificer can leverage that 6rh level ability.

Teleporting is cool and all and artificers doing this trick can make some serious coin as uber drivers type thing. But if I was going into the badlands I'd rather go with someone who can bring the heat than just bug out. It's a one trick pony just focusing on teleport.

Wand of Fireballs recharging that with 1st level spells has some mileage too. So not discounting the usefulness, but it's about more than teleport.

Unfortunately the Wand of Fireballs is in the "Wand" category not the "Wondrous Item" category, meaning that an Artificer cannot replicate a Wand of Fireballs RAW, which means that the Charge Magic Item feature of Magic Item Tinker doesn't apply as that only affects the Artificer's replicated magic items.

The Necklace of Fireballs is a Wondrous Item, albeit it's one that doesn't use the word "Charge" for it's limited uses (that don't recharge naturally) so technically also doesn't interact with Charge Magic Item, RAW.

They really like to put safety rails on Artificer features to an often annoying degree. It's part of what makes the Helm of Teleportation so notable, it's one of the few that's not kept locked away in the tallest cabinet along with the medicine or the toxic cleaning supplies. Granted, considering how people reacted to Artificers being capable of replicating Enspelled Armor and Weapons, we're frankly lucky they left the Wondrous Item category open at all.
