Which is better Rigify or MHX?

[garden]

Hello. I tried using both rigs a year ago. And everyone had their own problems. I think a lot has changed at the moment.
Which rig (+JCMs) is better and more correctly deformed when bending?
Which rig (+JCMs) is more productive in operation (more FPS)?

Actually mhx seems to get some freezing #1161. Once this is fixed both mhx and rigify are good enough in my opinion. But mhx is more similar to the daz rig thus should have better deformations. For 100% perfect jcms you should use the simple ik rig, but there are issues with feet jittering #1144.

note. Rigify has the issue that requires prebended limbs for ik to work, so you have to use “optimize pose for ik“. This is not needed for mhx.
