I find it so funny this was made. Not saying it's a bad idea, just funny.
Village as the worst is pretty self-explanatory and I'd wholly agree for the majority of boards. Even w/ TR/KC/etc., you'll often rather have a pseudo-Moat/Smithy than a Necropolis/+3 actions.
Ruined Market as #1 is pretty reasonable. I was immediately drawn to Survivors at first and thought of that as the best ruin until somewhat recently. RM is awesome(ish,) I'll often get Death Cart mostly in hopes I'll pick one up w/ no other buys(generally a bad idea tho.) But even w/ buys it can be a big deal, way better than pretty much nothing, 1 card, a copper that takes an action, or Survivors(usually.)
The only point I'd(tentatively,) contest is Abandoned Mine over Survivors. Giving Coppers themselves is considered junking, giving Coppers that take an action will generally be worse(and since Survivors are also an action it's fine to ignore that benefit to AM over Copper.) The odds can't be that great you'll get AM in a hand where you do significantly benefit from +$1(5 becoming 6 is often not much, for instance. You'll often want Lab over Gold anyways,) and can afford to play the action.
In heavy slog games, which aren't that unlikely w/ ruins, AM might get you to a negligible $ benchmark, while Survivors might at least do some cycling of crap. They also have some synergy w/ Tunnel, which is often a very important card when it shows up. Survivors can be useful against stuff like Rabble and Sea Hag too, and if you put the 2 cards back that can be good w/ stuff like Mystic or Wishing Well, actions permitting.
On the flip side you have the fact that putting the cards back means replaying Survivors w/ TR or something is wholly useless. That sucks, but you should have better actions to replay than ruins anyways. Really ruins are all generally bad tho, so how they're ranked bar the obvious bottom 2 and clear #1 is largely irrelevant.
