I have experience with both, and cut is definitely my preference. However I know a lot of African men aren't cut, as opposed to men who grew up here in Canada and USA, so I definitely would never say no on that basis.
In my experience though cut looks better, tastes better and feels better in my pussy. uncut have the tendency to slide in and out of their own foreskin which reduces the friction and feeling for me. Glans size and shape is also important as is a slight curve upwards.
