I have the JBJ Nano, but not the deluxe. Mine is the version with fans though, which supposedly has better components than the earlier version. I'm very happy with it so far. My only complaint would be higher lighting to sustain some LPS (brain, candy cane, etc), however the deluxe version solves that con. I have no comments with the AGA 16g, but with the Nano I'd say virtually nothing would have to be changed to sustain most
soft corals and some LPS. Maybe do the mini-jet mod to add more flow.
I have xenia which are doing great right now (see all kinds of little 'saplings' spreading throughout the tank) and just got some nice green/orange fiji polyps. Have two OC clowns, a cleaner shrimp and some hermits. Go for the nano, it's extremely simple and easy for a reef tank. I already want a 70+.
