Once the initial shakedown period has passed, in practice E-AB airplanes can fly where certified aircraft can. In a certified airplane, you still have to comply with 91.119.

I’ve only flown in a couple experimental—amateur-built aircraft; I think the current regs are a good balance of keeping “dangerous piece of shit” airplanes away from populated areas (once it’s flown out the initial operating hours, it’s probably not one) and allowing access to the National airspace system by others.
