Which machines do you hate fighting most in Forbidden West? And which are the most fun to fight?

I'm replaying Forbidden West right now and I've noticed distinct differences between the behavior of all the machines in combat, making some an absolute nightmare to fight with my play style (exclusively using hunter bows, sharpshoot bows and explosive bombs - no other weapons, no traps and pretty much no melee). I especially hate machines that can't hold still for even a second - Clawstriders and Tiderippers being the worst offenders in that regard. Since I go exclusively for weakpoint hits, those are incredibly annoying to fight. Also, fuck Rockbreakers.

On the other hand, I really enjoy fighting the big machines that, while not necessarily slow, utilize a more "stand your ground" style of combat. It gives me a true "David vs. Goliath" feeling, me being the agile little bee putting sting after sting into the big monster. Thunderjaws, Tremortusks, Dreadwings, Stormbirds. Those are really fun.

I'm curious to see how other players like or dislike fighting certain machines, since I can imagine that different playstyles really favor other matchups than mine.
