2017 F150 2" or 2.5" RWD Leveling Kit

I’ve been searching everywhere, but can’t seem to find a good answer. The question of all questions, “Should I do a 2” or 2.5" leveling kit (front end only)?"

I’ve been looking at 2" and 2.5" leveling kits for the front of my F-150, but can’t decide.

There seems to be a sweet spot between getting some lift and keeping the ride smooth.
