IMO the porta mount is a little more sturdy than the GS clone, the GS has quite a long diagonal arm which is a bit prone to flex with 100mm refractors.
I have a mate with a Toa 102, he found the GS mount a little too flexy and ended up modding the GS by replacing the alloy diagonal bit with a steel piece.
I'd be trying the OTA on both if you can before making a decision.
