Here's how I would rate them.
13 dark ages
None of the cards really stand out to me as good cards
12 seaside
Same problem with dark ages except for not as bad
11 dominion
Too basic and boring
10 prosperity
Same problem with dark ages and seaside but platinum and colony are good
9 nocturne
Some are good some are bad
8 guilds
Same problem with nocturne but there are more good ones.
7 intrigue
I like victory cards that don't clog up your hand
6 adventures
Travellers are cool but slow
5 hinterlands
Only a few useless cards
4 promo
Really interesting
3 cornucopia
Really powerful cards, and prizes
2 empires
Really wealthy, also very useful cards
1 alchemy
Almost every single one is in my top 20
