I'm thinking maybe he meant pros and cons performance vs. problems caused by the mods. Just a guess on my part!
For me, I think knowing the SRT is available now for 4 model years, and knowing what a reliable engine the 392 is, I'd tend to look for a used SRT vs. a SC in my 5.7. I guess it's a math question to some extent, what's the residual value of the '17 R/T, add the cost of the supercharger, then how much more would you have to spend to get a used SRT.
Then again, the cool factor and sound of the super charger could be awesome.
