from what i've seen, not really? it takes a long rest to infuse literally anything and you basically only get 2 infusion options per infusion slot. infusions seem to be less "temporary items to fit the specific scenario" and more a stand-in for an actually functional crafting system.
i was also speaking thematically - what's the point of playing as a magic item craftsmen when literally every martial character already has (effectively) crafting their own magic items baked into their class? the entire idea just feels kind of redundant at that point.
Thematically what's the point of wildshape when a wizard/sorcerer/warlock can polymorph?
It's a similar effect but applied differently.
But, as I said, I've never played a 5e artificer so if their thing is really just crafting permanent magical items for the party then I guess it's too much of an overlap.
