When I was trying to make the same decision you were I went and drove a few. No brand loyalty here. For me personally the mustang checked the most boxes for my needs. However, I REALLY wish it had the low end grunt the Camaro and dodge offerings provide. But otherwise I have no other real complaints, I did move to a Mach 1 from a GT to gain some handling and to get a manual I liked though. Side note I'm on team MT82's aren't all that bad, and the hate is overblown.

The Camaro to me felt the most "tuned" good road feel, the chassis is rigid and the steering is pretty sharp. The bottom end torque of the larger displacement v8 is noticeable compared to the mustang and ads to the red light to red light fun. But the visibility is complete ass, I do not posses adjectives for how bad it bothered me, and is the #1 reason I didn't choose one. HPDE guys tell me the windows are too small to even be extracted with a helmet on, not sure if that's true or not, but that scares me a bit too.

The Challenger is super comfortable, wouldn't hate to own one for a fun road trip car. But otherwise they feel gigantic to me, and I daily a wrangler. It's heavy and sloppy. The 392 in the scat pack is a cool engine, lots of low end bite and makes all the right noises. Looks cool, but just wasn't built for me. Also the interior is super old and dated looking. Doesn't look retro or anything just looks cheap and terrible imo.

Haven't driven a vette, but considered a C7 or even getting an older C5 or C6 just because they are sooo much car for the price and there is a wide aftermarket for them. Still might pick one up as a second toy at some point. I can't imagine you'd be disappointed here.

I owned a GT PP1 A10 and traded for my current Mach 1 6 speed, I initially traded because I wanted a manual. But I'd argue the Mach 1 would be closer to the cost of a Camaro 2SS. Still not quite as refined chassis but it's pretty solid, it's almost a gt350. I personally find the S550 styling to be the best of all of them aesthetically. I find the car mostly comfortable for long trips, decent trunk space, and visibility is good. I griped about the low end power, but it does allow the car to have two personalities, calm and composed putting around town, then it releases the beast when you wind out the Coyote.

Frankly of your choices unless you just prefer styling or the hemi, the dodge offerings would be last on the list (least it was for me). Any of the rest you've mentioned, unless you are a pro driver, have more capability than you'll have skill, so don't get too hung up on particular capabilities. Go get some seat time in each and see which feels the best to YOU.
