That's hard to decide, I think I'll go with Sal though.
As for the bugs (and things that bug me), I've found the following:
-Somehow managed to have two transforms on Jeqblac at once (imp + wolf) It goes back to normal when I stop the immitation
-Fhey had a point where she ignored her fullness, being able to grow to size 100 without even increasing her cap. I couldn't treat overstuffed nor give her food. Solved it by offering her to big toad
-Mushrooms are missing a transform immunity on their second form, or don't go into third at all
-Kip stones can be blocked with following allies, which takes away lots of the challenge
-Sometimes allies don't follow visually when leaving the town
-Well fed doesn't give Jeqblac a bonus in closeness points
-after reviving waifs, their permanent "ailments" are gone (like scales for Sal)
-Lenwhales wide girth still works when she's being eaten, which doesn't make much sense
-There are no places to switch waifs in the tower when going back in ch.7
