Upgrades to suites is a part of the Starwood program for their Platinums. Of course it depends on the type of hotels you are staying at. I do believe Hyatt also provides for some suite upgrades as well.
If you are staying 250 nights a year, you can try both out and see which gives you what you prefer.
