I have the 215 Oceanic. I like it a lot - true you won't get quite as good light penetration to the bottom but the visual impact is stunning. Also the oceanic one uses 5/8" thick glass and has no center brace so it's very easy to work on the tank. Downside is the weight and cost but it is very very very solid IME. You are welcome to stop by and take a look at mine if you want to see what they look like full of water.
