Yes is an easy choice for me. Fragile was listened to a lot back in the late 70s early 80s. At that time, the only Genesis I was aware of was the poppy stuff. I recently went back and listened to their early stuff, and didn't get it. I should probably listen again.
As for Yes, seeing them in the round at the Rosement Horizon on the Union Tour in 1991 is still one of my favorite shows. Round, rotating stage, with current and previous members on stage. So, Howe and Rabin, White and Bruford, Kaye and Wakeman.
