I don't think it's even arguable that Steph peaked higher than Kobe, there's too many supporting points to make for Steph and not nearly as many in favor of Kobe...
I'd still favor Kobe right now historically, because of the two points I mentioned earlier, I think the Comeback Kobe run is one of the strongest individual cases any GOAT can make considering all the noise around him (aftermath of rape case, beefing with Phil, beefing with front office, can't win without Shaq narrative) and the relative talent on his team in comparison to other GOATs when they won...
And the fact he was an elite player for somewhere between 12-15 years. Steph is "only" at 9 years as an elite player, and I'm using "only" facetiously because that's healthy longevity of nearly a decade. Steph is knocking on that Kobe door easily though, if he extends his prime another year or two and there's more information to add into the evaluation of his career, I'll probably change my opinion...
What all of you are missing about kobe's peak is that we really never got to see his full peak cause he played with shaq
The prime peak that people evaluate kobe is 29-31, which is still saying alot if you consider most peak primes are around 26-29 years old, then you start to slowly go downhill athletically out your prime from 30-33 years old.
Kobe peek prime was 2004-2007 which only ones of those he had a decent team an lost in the finals, the rest of those years, his team was trash in a ultra competitive west, phil and shaq gone, the coach they had retired in the middle of season, his second best player was Lamar odom followed by kame brown
By the time lakers rebuilt that team to championship level Kobe was 29.
Look at competition in the west at the time Kobe went to three straight finals
Tim, Parker, Ginobili spurs
Anthony, Iverson-nuggets
Nowitzki-kid-mavericks
Nash, Stoudemire, diaw-sun's
All these team had more talented team then the lakers besides Mavericks
With steph this is completely different, during the first for warrior championship runs they undisputed had the best team, most talented roster in the league which really how they beat lebron.
Even this year the warriors have most talented roster in league, leads to more 1 on 1 defense which clay, curry all benifit from
Kobe routinely on a night in night basis faced double, triple teams, there's a reason why Kobe is called the best difficult shot maker
Steph playing along side clay who is arguably the second to 4th greatest shooter of all time, and Durant who is a top 15 great of all time allowed steph to play free of double teams, even now with clay and poole, teams can't collapse on steph cause the others will make them pay.
The only time steph an Kobe had a equal playing field is when Kobe had shaq and you seen those results 3 peat champs...
