I can vouch for the PN suit as long as all you need is previs quality data (feet sliding, snapping to the floor) for a single person. I was able to get some production level quality out of it when the specs fit that very narrow range. The finger data is very good for the price. If you're operating at any kind of scale, you still might want to buy and setup a mocap suit, though. The straps can slide pretty easily and causing calibration issues. Their data processing is currently very lacking as are the help forums. Also, Axis Neuron isn't very nice to work from a TD/dev perspective, whereas most other systems have capture software that allows better integration into your pipeline. I'd expect these things to improve over time, though.
If you need to capture multiple performers and/or any props, require better fidelity motion, or are expected to deliver a lot of data, just go with an optical system. Vicon and Optitrack are probably your best options. On the processing side, you should also consider that you can now do marker clean-up/solving in Maya with PeelSolve and https://github.com/mocap-ca/cleanup in addition to existing toolsets in Motionbuilder, and Blade/Motive. All of these options offer acceptable opportunities for pipeline integration and automation.
