I don't think so, not sure what general concensus is though.
They are something of a 'generalist' class though, so I can see them lacking in raw power.
Magic in PF2e is lackluster in damage output, leading some to call casters weak. I don't think that's true, but casters do face challenges related to damage, and to needing to work around enemy saves types, and needing to deal with the fact that controlling the battlefield, and managing buffs/debuffs requires more thought than just dps.
And, since they are casters, the eidolon can't be as strong as a pure martial.
But since they're a bounded caster, the can struggle to actually have enough spells available to be able to bring ideal spells to bear each fight.
Add to that splitting their gold between martial items and caster items, and they'll be lagging a level or two behind on one or the other.
And just, their core class feature of getting 4 actions semi-split across 2 bodies that share a health pool, is complicated to manage.
All of that adds up to a class that is high-complexity across multiple fronts, in a system that's well balanced if classes are played well. So you, the player, needs to spend more time and energy planning, shopping, making decisions, to end up being as powerful as the fighter. I can see that not sitting well with some people.
For me, that's what I like about PF2e; the complicated classes aren't just OP if played to their fullest, so I, as the most invested player at the table, can go HAM without ruining other, less invested player's fun.
