Pretty sure I said they're all great, but I'm not stupid enough to think that Kobe is somehow more special than Kareem or Magic.
We've seen a player like Kobe before, his name was Jordan. Others have been amazing scorers, maybe not on Kobe's level or with his type of game, but we've seen them. The closest thing we have to Magic is Lebron, and even he is nowhere close in terms of Magic's post game, his court vision, his playmaking, etc. Magic has had no equal in terms of playmaking and court vision and he was 6'9". He is the BEST playmaker of all time.
Kareem had no equal in terms of career length and ability to score. There's a reason he's so far ahead of everyone in scoring, he managed to stay healthy and keep scoring late into his career. He had 6 rings, 6 MVPs, and an endless list of accomplishments. He utilized a shot that was damn near unguardable and now it's damn near impossible to replicate as no one can do it, at least not as well as he was doing it.
Your point is awful about level of competition. Kobe went through a harder western conference, but the finals matchups were all way easier aside from the Celtics. The Lakers in the 80s were playing against the the Bad Boy pistons, the equally stacked Celtics, and the Sixers. Some of the best teams of all time and they still got 5 rings out of it. Magic/Kareem also went to 9 finals in 12 years, do you understand the amount of fatigue that would put you through? The Heat were done after going to 4 straight, you could tell they were tired and slow, yet the Magic/Kareem, worthy, etc just kept on going, in particular Magic/Kareem that were since the first.
And your point about the supporting casts can get out. Kobe had amazing players around him too and the best coach of all time, we weren't killing anybody or doing much with we had bad supporting casts around Kobe. HE was still playing amazing and managed to get us to the playoffs, but nothing was accomplished.
