In the past, I've had both the RSM 34g and the 14g biocube.
The Red Sea Max was one of my favorite tanks. Although it had quirks here and there, I loved how simple it was to use. The Skimmer was problematic from time to time, but hey, it was a REAL skimmer! In a Nano! The first 3-4 days all it did was shoot out microbubbles into the tank, but after that it started churning out skimmate pretty well.
The T5 lights did a great job of keeping my corals happy, though it was hard to keep SPS, even up high. Even with the two strong powerheads, it still could have used more flow.
Yesterday I bought a 28g nano cube Quad CF. It was a screaming deal from the doc's and I can't wait for it to ship so I can set it up. It's going to replace my 20g as my main tank, and I'm going to put an angler in the 20g. My wife thinks they're cute.
