West - Denver - four seasons v. Ritz Carlton

Have a trip to Denver comming up and in the past have always stayed at the ritz, but I have been there since the four seasons opened. I'm just going to be out to run the marathon so location isn't really a factor ( they are about the same distance from the race).
Price is very close so that isn't a factor. (ritz is a few dollars cheaper)

I believe the base rooms at the ritz are slightly larger, but the fs is a newer property.

Has anyone stayed at both. And which do you prefer?

I've only stayed at the Ritz and it's beautiful.
