Stumps Reverse Flow Platinum Series or Shirley Fabrication

[TimmonsTravis83]

I'm torn a little bit and looking for insight. Have the opportunity to look at a Stumps Platinum series (RF) and a Shirley Fab cabinet model built like a tank. Been looking to get into a stick burner, and I know the GF (stumps) but you can use mini splits. What is the best way to go? I already have a GF cabinet smoker, but Im wondering does a true stick burner impart that much more flavor?

TIA..
