Was about to make a comment and after reading yours didnt need to. You said it all for me !They are two entirely different cars. If you want to drag race, the Hellcat is a good choice IF you can find a way to get it to hook up so you can get the power down. It won't perform on a road course. The GT350 is great on a road course, but only so so at drag racing. If you want to do both, and don't have the budget for a mid six figure car, look at the Z06 Corvette.
