I would say convenience and use case are just as important. A crescent wrench is non marring unlike alligator jaws or vise grips. It's also perfectly fine for low torque applications. It isn't for torquing lug nuts.

I have a wonderful wrench and socket set in standard and metric measures. It's in a nice case on a shelf in my garage. My crescent wrenches are hanging 5 feet away on a pegboard.

I needed to loosen an RP-SMA connector the other day. What size is that nut? Do I want to break out my wrenches and fiddle? Nope, the nut is only just beyond finger tight so two crescent wrenches and 5 seconds to get it off.
