I would disagree. There are 2 ratios for aftermarket T56's, and if you look at the "better real world" geared T56 vs 3650 it's a good improvement
1st 2.97 3.38
2nd 2.10 2.00
3rd 1.43 1.32
4th 1.00 1.00
5th .74 .62
6th .50

So sure, if you live your life one holeshot at a time you loose out on first. But every other gear(save 4th obviously) is better off, even if they're not tighter and 6th gets you an even taller overdrive for more relaxed cruising. This is all ignoring another real world point. that the aftermarket T56 Magnum's just wont quit. They laugh at 300hp.

The MT82 is a different beast for a reason. You're right, it's exponentially more aggressive and tighter spread. It's been matched to the 5.0 powerband. But the reality is the Mach engine, unless it's been opened up, isn't a 7000k rpm engine. Look at a stock dyno and the redline being 6800 is actually a bit generous. A 5.0 peaks at 6500, pulls to 7000 effortlessly, and although vvt works wonders isn't a torque monster like the GM 6.0/6.2/Hemi 5.7/6.4. So the MT82 helps it get in the peaky powerband as quick as possible, and keeps it there. Optional 3.73's only add fuel to the fire.

Also real world: Although I haven't heard tons about the 2015+ version, the MT82 has a documented spotty track record. The T56 may not be buttery smooth, but the 2.97 1st .50 6th version with 4.10+ rear is an aggressive, built to last, and daily driveable option. Can even run 4.56's with that overdrive if you wanted with little downside.
Edit: Now if you meant picking up a low mileage Cobra T56 no, its ratios offer no improvement and durability while much better, would be only a small boost compared to the aftermarket T56 magnum's(or Magnum XL as I think they call them).
