The mechanical web shooters are kinda redundant 90% of the time since he's just shooting single strands, but they're actually a good explanation for some of the crazier shit Spidey can do with his webs from time to time.
For all their faults the Tom Holland films actually do a really good job of justifying the mechanical shooters since he switches cartridges and web types all the time, it's not something he'd realistically be able to control if it was organic.
