Both shows have been off the air for more than a decade and a half. Why approach it in a console war-like way? Why the dichotomy of (primarily) 90s sitcoms?
Definitely Seinfeld. Huge fan of that show, and I barely got exposed to it when it was originally airing. I think I was in my closing years of high school when I got into it (2003ish).
I don't really mind Friends though. It's funny. Never got super into it but I've dabbled here and there.
Seinfeld easily. My friend loves Friends and made me watch a couple episodes with her and I didn't laugh at anything. I can rewatch Seinfeld episodes I've seen multiple times and they still get me cracking up.
