I can only speak from my personal experience and the rigs that I have owned.
I had a Swiss Made Actioncam, a Tiffen Ultra2c and an Arri Artemis / Trinity prior to my current Pro rig and
the Pro is by far the best I have ever owned. I really enjoy the simplicity of the design and the 'feel' of the precision engineering.
Of the above Pro has also shown to have by far the best support.
