I just looked at the Oben website, it may be comparable in quality to the big names, but it isn't comparable in features. It looks like a copy of one of the older Manfrotto heads.
It has a "single action" knob. That means it doesn't have separate controls for panning and drag adjustment separate from the main tension knob. At a minimum, you really want a separate panning control knob.
It only supports 26lbs. The big names are rated for far more than that and you really want a very strong locking mechanism to avoid creep - the tendency of the ball head to shift slightly under load when you remove your hand from the camera or lens even after you have tightened it down. It's a common problem in many less expensive ball heads.
