You don't have to switch, you can dualboot if you have some disk space to spare.
Unfortunately the only rolling-release distro I've ever used for more than 10 minutes is Arch Linux, which is not "easy to use"; it's not hard, but you have to tinker with it every now and then (especially in the beginning, since you have to set everything up) - if you run pacman
updates without looking at the archlinux.org frontpage beforehand you might find yourself with a malfunctioning bootloader or something on that nature.
AL updates are known for breaking things a few times, but in my opinion it offers a good compromise between DIY and ... y'know, Ubuntu.
