I've owned both rimless and eurobraced and I definitely prefer rimless. I'm currently operating with a Red Sea Reefer 250 and don't find it an issue keeping water in the tank. The biggest drawback for the eurobracing to me is that any bubbles that break near the surface create a film on the glass and condensation can also be an issue depending on the system - all in all leading to a pretty big eye sore unless you're constantly wiping it down. From a simple aesthetic approach I don't see how bracing can be preferable but from a practical perspective I can see why people like them.
