11 months ago: I use Genesis Studiopress themes personally. The support is fantastic, themes are plentiful and tweaking the designs is simple, even for someone with little or no knowledge of coding.
I have used Thesis, but much prefer Genesis. As to not being unique–clear instructions are provided (and a ton of support) to get the look you want. Any theme out there is likely to be used by more than one person. With my theme package, Genesis is kept up to date. Being part of an active group (rather than something that was created years ago and hasn’t been kept up) is really important to me. I don’t have the time or knowledge to maintain the code.
With Genesis, “hacks” are possible via recognized means that don’t cause your site to crash as soon as another update to Wordpress rolls out (which is frequently).
