I put the UF8 a bit above above the Keystation 88 pro for playability - both are quite different - personal preference etc etc - I just prefer a bit more weight and rebound which the UF8 has over the Keystation. But the Yamaha P70 is in a completely different league altogether! Ok it's about a quarter as much again price wise as either of the other two but I'd say much better value if playing action is the main consideration.
For the cheapest 'pro' (an awful term, sorry) 88 key h/action keyboard for piano/orchestral libraries etc this looks like the one to me.
It will require separate mod and pitch bend if needed - I never use pitch bend and prefer a separate knob for mod anyway.
Hope that's of some use to anyone else in my position
