Myself, I've never seen UC because of the lower quality of animation and I've gotten through about 4 episodes of SEED before putting it on extended hiatus until I'm bored enough to try again. That said, reading through this forum's sparked an interest in me to hit up UC, especially since so many of you are of the opinion that it trumps SEED (and every other Gundam), regardless of animation.

Lower quality of animation!? I'd agree if you were just talking about Mobile Suit Gundam and/or Zeta (some parts were clearly lower-budget), but fi you think that applies to all of UC, you probably haven't watched most of it.
Of course the newer UC series (and by newer I mean made in the 90s) like 0083 and 08th MS Team will have better animation, but even older series like 0080 and ZZ (leaving the story aside) are very well animated by hand. Animation-wise I'd easily pick one of those over Seed (such lovely
template frames and recycled animation, won't you agree?).
While 00 is a pretty piece of artwork and definitely quite a sight in HD, Char's Counterattack and F91 still trump it in animation, IMO.
