Honestly, if you really look at what they entail, I really don't recognize any points of differentiation between the three main nanocube manufacturers. They're all pretty much the same, the only difference being the lighting--but that's a regular versus deluxe issue, not a brand issue. I think all 3 of them would make decent planted tanks, though i've only used them for reefs.
I am pretty new on the planted side of things, but I think the relative value of the built in sump they have in the back is less valuable with FW than it is with SW. As a consequence, if I were nano shopping I'd save money by getting something like the Finnex 8G nano, which is $60 for tank and light. As a fan of open tops, I like the look a bit better and it's easier on the budget. Just my two cents.
