So about the suit: it's most hindered in the forward motion of the legs, which is a pity because you can't get the crazy crouches and flailing web-swinging legs with high fidelity, but this was not the least bit unexpected.
The material rebounds just like the Advanced, obviously will take longer if left in place. Be particularly careful at the back of the knees. You need to move the material out of the way of the joint, hips, knees, whatever. It also helps to pivot the closest joint or joints in the opposite direction to pull material away from where you bend.
The neck creasing is a real thing. In some positions it actually heightens realism by looking like crazy superhero tendons, others not so much. It's something you need to deal with by smoothing, moving, flexing.
Can you make this figure expressive? 100%. Can you make it do whatever a spider can? Nope. Make peace with it.
I didn't spend a ton of time, just testing and playing a bit to see. Joints are pretty tight but outside of a vanilla running pose those ankles won't hold him on one foot in a lot of positions (not that it's necessary) as the figure is heavy-ish.
