Having read the list again I've removed the "probably".
I'm quite sure that a F Type, an M2 and a GTR will all be miles better in terms of chassis dynamics. And if you get out of an Exige into a Mustang, it will probably make the Mustang feel like a wet flannel.
I'd get an B7 RS4 honestly. It will be quick, it will sound great, it will be well equipped, and it will be fun. But most importantly, you probably won't miss it when you get rid of it and step into your new 'Stang.
You forget I've driven most of these cars, and you could not be further from the truth in some respects, people who have driven the modern Mustang and the other cars will know it strengths and weaknesses. For instance the GTR, the Mustang has a much keener front-end and basically turns in better, its also easier to hold through a corner on the throttle and the driving dynamics are very much old school but pretty good and you forget my car is not exactly standard, I dialled all the weaknesses out.
In short there really is no perfect car, well there is Porsche GT3, but thats the only one I can think off, though unfortunately it has grown a touch too big but its not quite as big as a BMW M4, Mustang or GTR, but its no longer the ideal size like a BMW M2, Porsche 911/Cayman 997/987 generation. But the GT3 is the closest you will get, its also why they are all 120k plus for second hand examples.
Lets see if I move the Mustang early I have an opportunity to maybe jump in and out of a few vehicles whilst I wait, my only real complaint about the Mustang is its a manual, its not a bad manual, I just dislike manuals I am finding as I get older in a daily car. The size of it does not really bother me on my daily commute, only time its an issue if blasting down a road you don't know which is quite narrow, as such your more cautious and its performance in the wet is lack lustre as the chassis/weight and driven wheels just don't suite wet performance driving. But as a car for the daily commute it probably brings more smiles to my face than any other car because I can push it and enjoy it and grin like crazy or I can just drive down the street at 20mph and still be grinning like crazy, this is where it wins hands down over most other cars. If I want driving dynamics I already have one of the best on my drive in the E46 M3 which to be frank takes a massive dump on most modern cars.
