not all bikes are equal,
started on 26rs like most then got my first 29 (Lenz Leviathan) which felt like I was 10ft high.
After a few trials found the perfect 29r (Banshee Prime) but then found more love with a 29+ Carver and 29 SS Niner, which then I switched to 27.5+ for the Banshee and couldn't ride my Klein Rascal or Ellsworth Specialist.
Then my buddy sold me his first Gen Ibis Mojo and I fell back in love with 26r for a bit. Reforked the Ellsworth but the Klein still feels terrible.
In the end ride what you got, trends and preferences change. Wheel sizes don't mount up to a hill of bean
