MVP is great if you fly routes that are easy upgrades (SAN-BOS, SAN-HNL, etc). Whether it is worth flying cross country for the lowest tier elite status is up to whether or not you will actually use the benefit next year.
I've been MVP for a couple years now and enjoy the SDC policy, preferred seats, call centre, and occasional upgrades. I personally wouldn't do a MR for it, but thoroughly enjoy the benefits nonetheless.
