I like Melo's game better...last head to head matchup between the two,Melo outplayed Lebron.A lot depends on officiating from game to game.If the game is officiated with the best NBA officials i think Melo would win 6out10.Lebron &Kobe gets a lot of calls that Melo,Wade,and Pierce will not get.Lebron has the edge with the media,officials,etc.with Kobe running a close.
One other thing,ask yourself when deciding between players who do you want taking the last shot in a close game...in the list of players here,i'll list them in my order: 1.Pierce
2.Kobe
3.Melo
4.Wade
5.Durant
6.Lebron
