The MultiRom is quickly becoming one of the most popular. The main feature of MultiROM is the ability to flash and install several roms at once that you can flash back and forth between without wiping data. This is pretty cool because normally you would have to flash a rom, set it up the way you like, then nandroid backup your setup then flash another rom and repeat the whole cycle several times to end up with the same kind of result. This makes things much easier and much cleaner. Now this rom is on the HTC One M8! This rom is still in Beta so be mindful of that. Head to the link below to give it a try.
