I have been very happy with the Really Right Stuff ball heads in combination with their lever quick release clamps. You should study their offerings, and look through their site for information on ball heads and Arca Swiss compatible clamps. Then, stay with better brands than you have previously chosen as you consider what to get. A quality ball head from one of the better manufacturers will last many decades, and going with Arca Swiss compatibility will allow you to adapt to most any camera that comes along.
And I would think you should consider a good ball head over any adaptation of a gimbal head. I own both, and would never consider mounting a camera body on my gimbal head. Each type of head is designed for specific intended uses, and a good ball head is where to start.
