Thats a tough one. I have a SRT but I imagine the non SRT's brake and handle close to the SRT. Perhaps have a better ride. For me this car is a toy. An enabler. I bought it thinking it could be a daily driver, and it could, but what it does best is go. So I protect it by not going places where they have parking wars, etc. and go to the race track every chance I get. Auto-x and 1/4 mile. That is where it's real talent lies. And the fact that afterwards while others are loading their cars on trailers, your putting the air on and adjusting the radio for the cruise home. If you don't plan on driving the SRT fast, don't trade. Stay with what you have. If you truly enjoy and are thrilled by the handling and acceleration, get the SRT.
JMO of course.
