I voted "sometimes." I love my gear wrenches, and have a couple sets: Craftsman full-polish, and GearWrench brand, both regular and stubby.
'54 Buick, '57 Chevy gasser, '56 Chevy project cars. '62 Suburban daily driver, and I just got a '73 Duster. The ratchet wrenches are the first grab in my box.
Those vehicles all have a fair amount of stuck, rusted and otherwise hard-to-move fasteners.
I'll go after the visually obvious hard ones with a 6-point socket and ratchet/breaker bar. If it's a place where only a wrench will fit, the GearWrench is the first grab, unless I'm concerned with rounding off the bolt or nut--then I swap to a 6-point box wrench.
I also have a set of the socket adapters, to turn the GearWrench into thin profile fine-tooth ratchets, and I've used those to bust loose stubborn fasteners.
I also keep a set of GearWrench brand wrenches in my junkyard/road trip tool box...and they've gotten a fair amount of abuse, because in the junk yard, you've gotta make due with what you have, and sometimes that's not pretty.
