Cimarron vs. Drake

My wife picked out a Toto Drake at a showroom and then contacted a plumber about installation. He suggested that the Drake was overpriced (whether by the showroom or the manufacturer was not clear) and recommended the Kohler Cimarron instead. We live where a 1.6 toilet is required and good flushing is important to us. My reading of the separate Drake and Cimarron forums suggests that we should stick with the Toto Drake but the problem with reviews is that they are usually only written by people with complaints. Any opinions on a direct comparison?

I've used both.
The Drake is much better then the Cimarron.

The Drake sells itself.
Once you have one, you want more.

I can't say that about the Cimarron.
You'll be the one with the plunger.
Be glad she picked the Drake.
