Toto differences?

Are there any real differences in the performance of one piece Toto Plymouth (which I prefer aesthetically) and the Toto Dartmouth or Carollton. I know that there are some differences in the MaP ratings, but all are above 600. Are there differences in noise level or anything else that would be noticeable?

It's all pretty close.

I like the Plymouth too, though I do sell quite a few Dartmouth toilets too.
You will notice that the working parts of these toilets are very similar.
