I don't know if I'd call s1 or s2 worse than the other. I'd say they're equal. Different, but complementary. It comes down to which you prefer (episodic or arc-based.)
It's probably hard for me to judge because I watched both seasons without really thinking and analyzing everything, or indeed even knowing where the season breaks were. It was also before I really used the internet and turned into one of those internet curmudgeons that nitpicks the shit out of everything.
(This is kinda like how I view Seinfeld, some people can't stand the later seasons but TBH I was hard pressed to tell any sort of difference (aside from s1/s2) in any of the episodes.)
