G.O.A.T.
Disagree. We're still at the early stages of their rivalry & we don't know what's gonna happen next. Both are neck & neck, with Sinner having the technical matchup advantage & is the better ballstriker, as well as the better baseliner of the two; but Alcaraz has the benefit of being the better athlete, superior shotmaker & slightly more clutch.
I expect the rivalry to be as close as possible for rhe foreseeable future unless one of them declines sharply due to physical issues or otherwise.
If Alcaraz is major injury free till 30 then Sinner will be his pigeon, the so called matchup advantage which you say for Sinner is non existent... when was the last time Sinner beat Alcaraz in a slam ? ...
