Agree on all points - MMA being the winner is obvious.
One thing to keep in mind is that a lot of these PETG filaments are not true PETG's.
I didn't get a chance to watch with sound on, but curious if he verified it was really PETG
A lot of the PETG's are really PLA/PETG mixes.
Or event mostly PLA with some small PETG. Or something else entirely.
I actually have had filament claim to be 100% PETG, but it dissolved almost instantly in acetone, so not sure what it was, since even PLA doesn't really do that.
Often you can also tell it's not really PETG by the claimed glass transition temperature/etc, but ....
