It really comes down to how you use the car and your tolerance for compromise.

If it’s an everyday driver, there are points in favor of the Boss. Better visibility, better and more useable trunk space. There are points that work against the Boss. Most prominent (in my opinion) is the MT82. Every Mustang I’ve driven with MT82 has disappointed me. Last was a 2019 Bullitt. Keep in mind that the shifter is the thing that you come in contact with most in an MT equipped car, and if you hate it, it ruins the driving experience. Love the cue ball knob in the Bullitt, but absolutely hated the clutch feel and the shift feel. In contrast, the Tremec in the 1LE is how MTs are s’posed to feel.

If it’s a weekend warrior, the things that work in favor of the Boss are the exhaust note and the engine feel and power. The things that work against it are the MT82 (did I mention that I hate it?) and the live axle suspension. Stay away from Cars and Coffee .

If it’s a track car, I’d probably change out the transmission and call it a day. I’m not sure how the live axle impacts it on the track and I hear that Boss does kick ass on the track out of the box. If I were to find that the live axle is an issue, Steeda has a long history of upfitting Mustang suspensions for better performance.

Just my 2 cents based on my preferences.
