As other have suggested, if the shoe fits...
From your "getting back into climbing" statement I would suggest technical nuances are not that important. Personally, I love 5.10 but that's purely because they fit my feet perfectly. Another reason I favour them is that they don't stretch too much being made from synthetic hide, though other brands may have followed this in recent years. I've never understood why people cram their feet into a size (or two) too small when they are not climbing near the living end, snug and no sloppiness is fine for most people.
