I've been installing a lot of the Toto Drake toilets at $199.99
That price will be going up in about a month.
You don't mention the Toto, but it's the best out there right now.
Or you can pick up a Cadet 3 and pull both pieces from the box to inspect before bringing it home.
The Cimarron will plug more often the the Toto Drake and the Cadet 3.
I don't like the trapway design on the Kohler.
In Tennessee, I've used Southern Supply.
The current Cimarron is better then the 1995 builder grade toilets, so it would be an improvement over what you have, not what I would call best, but better then your 95 bowls.
