i had the 28g biocube, I liked it, the stock tank gives you 3 36w pcs so you will probably end up upgrading your lighting, The biocube ballast are notorious for going out i replaced 3 of them in the 3 years i had them. Also fans get pretty noisy after a while, there easy to replace at about $12 dollars per fan at a computer store. Also after a while the tank seemed a little bit small in size which is why i am now upgrading, i think the red sea max has t5 lighting and its a bit bigger. If price wasnt a factor i probably would have went with that.
