Drake vs. EcoUltramax

With my city's toilet replacement rebate, I can get the EcoUltramax for about the same price as the (non-Eco) Drake. Does anyone have any experience with the two to the point they could recommend one over the other? I prefer the look of the EcoUltramax, but I would not want to sacrifice much performance. Thanks for any insight.

The Eco Drake, Eco Ultramax, Eco Supreme and Eco Nexus work well.

I have a Eco Drake installed in the main bath at the moment.

So would you say there is no (or at least only a minimal) performance drop-off from the Drake to the Eco Drake? Thank you again for the help.
