I love GURPS, and for a long time in the Dark Ages I played it probably on a par with Hero (I especially liked it for non-super powered things, and I used GURPS Wild Cards quite a bit).
With the resurgence of Hero 5th, I still follow GURPS, but I'm doing more of my gaming in Hero. GURPS has got way more support, but I think the Hero system suits me better, and it's catching up fast. Once I realized I didn't have to write up full balanced character sheets for every villager the PCs might possibly encounter, Hero worked a lot better for me.
Pyramid is absolutely great, though.
