I sold my KH 29er because it just didn’t have the tire availability I needed for muni riding. I also found that it was very high off the ground, which negated the advantage of being able to roll things well. I now have a 26" and a 24", I ride the 26" most days. I’m running a 2.5" tire now, but I just got a 3" Duro to try out. The 2.5" tire has a slightly higher volume than the largest 29er tire (Stout), which helps cushion the ride and allows lower air pressures which help with traction, float, and overcoming hard obstacles. Even with a 26" I still feel like I’m high off the ground for technical riding. I rode my 24" last week and it was far easier to ride, though it seemed kinda twitchy and it definitely doesn’t overcome obstacles like my 26".
I think a lot depends on what you ride in terms of terrain. I ride very rocky and rooty single track that requires a lot of repositioning, esp when it’s wet. Riding a 29er took away some of the maneuverability I needed. I could ride the 24" on everything, but with the 26" I can go faster and the ride is smoother, so sme benefits of the 29er while keeping some of the agility of the 24". One of the nice things abouta 26" is all the tire choice
