First things first this is my first post though I'm not new to the forum been reading them for years and have gotten a lot of help.

I ordered a 16 Lariat 502a with max tow (which probably won't be used much) which will be delivered in June. Not waiting on Ford they are waiting on me to get back to the states. Enough with the details. Here is the question I know the catch can thing has been debated and this isn't about that, but which one is better UPR or RX? I know opinions are like ***holes but any experiences would be greatly appreciated.
