Go with the Hellcat. If you want Real Horsepower and want to seat 4 people comfortably, it is pretty much a no brainer. I have 2013 SRT8 with a 6-Speed manual that is Plum Crazy Purple, that just rolled over 5,500 miles yesterday. Love It, seats my family of 4 VERY comfortably. My son is 6' tall and rides in the back seat regularly. Let's see the Fords and Chevys do that. Had a 2010 RT before that.
Good Luck
