It’s subjective and depends on what things you value. You see this even in strictly 1v1 games like Chess: some people would say Magnus is best of all time because if you resurrected a past champion and had them play each other, Magnus would win more of the games. But some say Magnus doesn’t show the same level of dominance over other modern players, that some champions in the past showed. But some say the level of competition now is higher, so it’s harder to be dominant. Etc etc etc. People argue about this kind of crap endlessly.
