I have no personal experience to speak from, but I've heard that aside from a couple very expensive resins like Wargamer, the water washable resins tend to be very brittle so I've avoided them so far.
I mostly use Sunlu ABS-Like. I can get it for $18/kg and it's easily the best ABS-like I've tried. Going to buy a bottle of SirayaTech Tenacious soon too to mix a little bit in with my regular resin (9 parts ABS, 1 part Tenacious) which should make my minis nearly indestructible without any noticeable detail loss.
YES, I fucking love this album!
NOW I CAN SEE THE WHAAAAAAAAAALES dun dun DUN dun DUN dun DUN
