Take a good physically look at both, Dji's gimbal are proper commerically designed stuff with moulded parts and rotary encoder for positioning, the cinestar ones look like some back yard invention.
Back yard invertion, LOL! I guess you don't own one. Cinestar gimbal is at the moment best MR gimbal available for professional aerial shooting if you need to lift anything bigger than NEX or GH2. It's very well designed gimbal allowing you to use cameras from go pro to EPIC. CineStar frame is designed to professionals who want to use highest quality parts in build and decide what controller, motors, esc:s like to use. I've had lot of problems with plastic flexible arms of F550 and don't want that same behavior from bigger frame i use for shooting video. CS does not bend and twist and allows you to lift what ever you need with setup what ever you like to without worries.

At the moment, with the Zenmuse Gimbal, you have a limited angle of uninterrupted view due to the fixed structure of the landing gear. If you need more movement you have to turn the whole bird in the air. Zenmuse works only together with a DJI FlightControl.
At the moment, Zenmuse only works with Panasonic GH2 or Sony NEX5/NEX7 cameras. This and the construction of the landing gear might change in future...
Cinestar 2- or 3-Axis Gimbal has a 360° uninterrupted view due to the construction of the landing gear. Cinestar is usable with a wide variety of cameras, free choice of FlightControl/Gimbal Stabilization.
Both are very good products. The question is not: What is better...the question is: WHAT DO YOU WANT...
