I would think you want a single hag - there's no way to deal with the curses, and you are going to get bogged down with them pretty badly - the game will go long thanks to both the curses and silk roads. The points are actually also not insignificant.
Double hag is too much, as the game is going long enough anyway, you want to be playing wharves pretty often after a point. You're going to need money, and your terminal space is limited. Venture is maybe a card you would want if you have lots of terminals already, but wharf is just so much better, I think you want it even if you already have two other terminals (and after a point, if you already have three - the duration nature makes it so that collisions are somewhat less likely than for normal terminals.
Having said all that, I would expect single hag to beat zero hags perhaps 2 to 1? A lot will still depend on what you did here.
In the actual game, I would also be somewhat suspicious of how late you were in getting wharf - my gut is that at least one of the masterpieces is better as a wharf, possibly also the feast. It actually doesn't make tons of sense to me the combination of masterpiece and feast - feast says "I really want wharf, and will sacrifice a silver for it", whilst masterpiece says "I will sacrifice wharf for a couple of silvers, even while picking up a copper"
