Overall a very fair comparison.
I would say that for completely new users that don't have a preexisting EOA, there is no good reason to go down the 7702+4337 path.
With 7702+4337 (as opposed to pure 4337) the huge benefit of friendlier and more forgiving key management schemes (biometrics, self-custodial account recovery, rotatable keys, no seed phrases needed, etc.), comes with the large security risk you mentioned, but offers no benefits (i.e. a history for airdrops) as they are completely new users.
And TBH, I don't think it's possible to resolve that inherent issue
