in the testing I've done, changing ESC didn't effect performance, however underrated ESC did experience higher temps and ESC's over 140°F tend to have shorter lifespans
Was I looking at the same test? You compared a 35amp ESC to a 60amp ESC and the 60amp ran faster! And I quote
"Turnigy 35A ESC + Turnigy 3300kV = 29.1 mph
HobbyWing 60A ESC + Tacon 3200kV = 29.6 mph"

those are different motors, the Tacon just performed better, trust me, I've swapped many ESC's out in my stock racers in an attempt to get more speed... specifically 45A Stock ESC's vs 120A ESC's and both ESC's produced the same performance when used on the same motor.

Doesn't a 2 pole have less cogging because less magnetic force which is why you can easily roll a 2 pole RC back and forth easily compared to a 4 pole? And for that same reason it also has less of a drag brake effect?

Not sure about that, I pretty much run sensored motors these days to mitigate any cogging issues... I don't think the number of poles will matter much, just some brands of motors tend to cog less than others and same goes for ESC's where HobbyWing has been my personal favorite and lately I've been having good luck with GoolRC motors too

As long as the motor power stays under the ESC limits I believe an ESC swap won't make much difference. DIfferent story when one of the two ESCs is at the end of it's abilities.

A MMP can handle quite more than 65A, not only during bursts. I use one in my 4x4 Pede with a Castle 2650Kv motor in it. It never had problems feeding that. On 3S, that motor eats up to 2000W.

Motor torque is equivalent to it's power. If you have a 2 pole motor which has the same power as a 4 pole one, the torque will be the same.
