I haven't stayed at the downtown location in 1.5 years or so, but our suite was newly redone then. Living room separated from the bedroom, and relatively nice. The low floor part of it stinks though.

As for the Music City Sheraton, I've stayed there dozens of times, always had a corner suite, but never the Presidential Suite, so nice job! I'd rate the staff and Plat treatment as an A, and there's plenty of space in the corner suites, but it's getting a little worn and will need a refurb sometime soon. Unless I need to be downtown (concert, meeting, etc), I'd much rather stay at the Music City. Oh, and it's free parking there, even if you're flying out and not staying there.
