For under $200?
I'm kind of partial to the Toto Dalton CST734F
It's comfort height, elongated, and with good performance.
It has good bowl rinse too.
If you want to drop another $100, you can go with it's big brother the Toto Drake CST744SL, 3/8" taller bowl, and even better performance.
The Kohler Cimarron is close, however it plugs more and could use better bowl wash.
