I tried both and i prefer Redis over Memcached except for very simple use cases. It is true that for a pure caching system Memcached is easier to setup, easier to scale and faster. But by just a small margin. On the opposite side, Redis provide a lot of primitive very fast and implemented in C that allow for more complex use cases. For instance, in one of the project I was following, the ability to merge two or more sorted set was pivotal in implementing a more efficient warm-up scheme. I could get the same result with Memcached and a software layer, but it would be less efficient in term of latency and bandwidth. Given these huge advantages, my choice is almost always Redis because I prefer to manage one system instead of two.
