It was my 1st grow so take my opinion for what its worth.
I grew and growing again the uberkush. There were 2 distinct phenotypes a lanky sativa type and a short bush like version. The 3 tall lanky plants went hermi on me without realizing it at the time. I found everything after I cut it all down. The short bushy ones I cloned and am trying them again, so far so good. I never smoked any kush crosses before so I can not compare it to anything, but it has a unique taste to it Almost a chemical taste hard for me to describe. It works for me though even though most of the plants energy went towards seed production. :(
Hope this helps somehow.
Edit: Yes he did stop selling them because of the hermi issues, kind of mentioned it off offhandedly in the middle of a big thread about uberkush
