>>12087250 Priceless Viewing Experience, I would say.
part of anime-watching is watching the current episode and discussing stuff with other viewers. if there's a group that's competent and up-to-date, i really can't think of any reason to wait for an incrementally better but much slower group. i'd probably just archive whichever i got.
if you aren't talking to anyone about it, sure, wait your months for your favored group to finish it up, no problem with that
