Agreed on the whole "category" thing. I'd have to say from a comfort category I love my seats - without comfort and control, I just can't enjoy the drive and the stock Boxster seats didn't fit my frame correctly.
For performance, I'd have to bump +1 on the Koni+H&R Spring suspension. Although the original drop was a bit too much at first, once I installed ~1/4" of spacers above the H&R Springs, I found the ride was a perfect balance of firmness, control, and dampening without being harsh.
A few pictures added.
