I have both myself, you can do more with the Apex but it's takes some time to figure out. The RK is much simpler to Program and set-up. Really depends on how complicated your system is IME...If you like to tinker and you have a bunch of equipment to run, go APEX...if you don't want to spend a bunch of time messing with things and your system is simple (lights, pumps, skimmer and maybe a reactor or two) KISS with the RK.
