Our 2018 C-Max has what we would consider well-tempered, not aggressive, regen braking. Pressing what I call the descent button on the gear lever invokes more deceleration force. But in normal Drive mode, we can coast smoothly up to a corner and turn without having to use much (if any) brake pedal. We really enjoy the handling aspect of the C-Max for that reason.
My wife's commute mileage after 30,000 miles is 49.8mpg with about 50% EV . Sorry I can't recall the Regen stats - which indirectly says it performs seamlessly.
