Mishimoto Catch Can or Teraflex Crankcase Vent System?

[DesertRunner]

For those who are running a catch can or vent system, which did you go with and why?

I have the spark knock issue and Jeep won't do anything about it. Hoping to get a root cause fix using one of the above.

I went with the UPR catch can and added a 4ft drain hose with a ball valve at the end of the hose.
I modified the bracket to add the drain hose .
The drain hose doubles it capacity eliminating any oil build up in the can. It all in the hose .
It completely eliminated my spark knock.
