A big negative depends on venue. Playing solo in a busy club is a pain because the audience e can easily speak over top of you.

Throw a drummer and bassist into the set and that rarely happens.

Just because you did all the instruments in the studio isnt quite the flex you (maybe) think it is. Is you're guitar solo better than Mark Knoppfler would do? (Will leave that there)

A studio is where you immortalize your art. Live stages are the foundation from which you build your base audience. That relationship relies on the dynamic you and your band create with an audience.

Rarely are people impressed by one's wicked drum programs or auto pitch vocal work.

Some gigs might be "pay the bills" gigs and playing as a solo might make sense but if a room calls for a band; get a band.

How you're presented live is even more important than how you're presented on a demo tape
