I'm one of those people that really doesn't care. I've had everything but + bikes and liked them all, currently have two 27.5ers one a FS and one a HT. If I were buying a HT today I'd go 29er. If I were buying a FS with some travel 130mm or more I'd go 27.5er while I"d go 29er if I wanted more of a XC full squish bike.
