The nice thing about high regen is that, when you need to panic stop, you have a lot of braking happening before you even reach the brake pedal. I consider this safer. The bad parts are that, when switching back and forth between ICE and EV, you'll expect or not expect the regen braking. It gets confusing and cuts smoothness. Also you have to have more constant pressure on the pedal. Replacing the return spring with a lighter one might make the driving physically easier.
