Vacuum Catch can: rb turbo or BMS

[rapter]

Is there any material performance difference between an RB external pcv kit and the revised Bms vacuum side kit?

These both seem to do the same thing and attach to the same areas of the pcv system.

Some threads seem to claim the rb turbo kit with mishimoto can collects a significant amount more oil than the bms but it is not clear if this statement is relevant to the new or old bms kit.

Which if the two kits perform better or are they the same ??
