I debate this all the time with a friend (by making the same list), but my view is basically that most fans are stupid and have no legitimate opinion on this matter. I know that argument more or less invalidates my opinion as well, but its sad that people who've never watched even Magic or Bird, some kids even Jordan, argue for Kobe and Lebron as best ever. I never saw Wilt, Russell, Oscar, Dr J, Jerry West, Elgin Baylor, and many other greats play, but to some it's like they don't even exist. For the record: Lebron is great, but he's no Magic, Bird, Wilt, or Russell. /end rant.
Interestingly, Jordan commented recently that "only" Duncan, Kobe, Dirk, and Lebron of the current era could play in the 1990s. Certainly a slight on Durant and Curry (is he ignoring Paul also?), and I disagree with his take, but interesting to see.
