So after having a few different mounts for my phone in the car, the one I thought I'd like the least so I tried last (aside from not trying Brodit) is the one I like the most.
Kenu AirFrame. Tiny. Cheap. Easy to use 1 handed. Quick & convenient to mount or remove from the vehicle.
I really think it's absolutely ideal. Also comes in 2 sizes/colors so there's one big enough for you folks who need a 5"+ screen for whatever reason
