Is Dominion 2nd Edition worth it if I already own the first edition?

Discussion on r/dominion and r/boardgames generally says yes if you play often: the 2nd Edition replaces several widely-disliked cards (Chancellor, Woodcutter, Feast, Spy, Thief, Adventurer) with stronger, more interactive ones and refreshes the art. Casual players who rarely break the box out can stick with 1st Edition or just buy the update pack.
