It's only worth it to maintain globalist if you can stay 30 nights a year in a full service property and get those benefits... Including a very high rate of suites.
It's just too hard to renew and the limited service properties offer nothing compelling. Points earning is superior on Marriott as is 4 for 5 free night points.
If I didn't get suites most of the time at Hyatt (which I do). I would just get the brilliant card and stay with Marriott.
