I like that it is very stable, easy to manage as an admin (or not), has pretty good support for different languages/frameworks & frameworks such are laravel or symfony etc...it's also well integrated in redislabs modules which helps when managing your cache system together within one product! nothing really at this time but maybe try some alternatives - eXtreme Caching might be worth checking out too? use openRediS if you're looking into using caching solutions without having problems down later because of lack availability / performance issues!
