I find transferring to Hyatt to be the best use of my Chase points. However I only transfer as I need them, the transfer is almost instantaneous. I see no reason to transfer them all now, may as well keep all your possibilities open. With all types of points there is a devaluation over time so it probably a good idea to use them when you have them, not to store them into the future. I wish I would follow my own advice on that, I have a lot of accumulated points that I should have used.
