Evenly mixed, if you look at all the results. Both solutions for wheel diameter work well, just in different ways. For taller guys, bigger wheels will feel more natural to a larger fraction of people because of the proportionality of those, but somebody wanting agility and travel for chunk may still prefer smaller wheels (conversely some riders prefer wagon wheels no matter what).
They roll things differently, with different characteristic feels. Big wheels have lower attack angles and tend to feel smoother over moderately rough stuff because less peak energy is involved in getting out of the way, but more unsprung mass and a lankier bike is always a tradeoff. Same deal with feeling in the bike (more bottom bracket drop) versus on the bike (less bb drop, but can initiate direction changes easier).
For my part, a 29er with 150/140mm travel is able to get me into and out of plenty of trouble, with good tires climbs technical stuff brilliantly, and with modern geometry I can goo stupid fast. Low speed tech and climbing switch backs is basically compromised (but I personally suck at that anyway), and it requires a lot of commitment for frolicking.
