Stick with the Dragon.
The plans are simpler, the tactics are more thematic, and the strategies and piece placements are more consistent across different Dragon lines than they are in the Najdorf. Also, the Najdorf is no simpler, tactically.
The Najdorf may give a slight...SLIGHT...edge at the GM level. But even there, you'll find Dragon devotees.
Until then, all the things that make the Dragon such a fun and interesting choice actually serve to make it a stronger defensive choice for most players than the Najdorf, since white is almost never going to be playing critical lines 15 moves deep against you. Against anyone "just playing chess," a little knowledge of the Dragon will carry you along way easier than a little knowledge of most Sicilians will.
Hello guys, so i've been playing the sicilian dragon for the past years with success but that's mainly because my opponents didn't play the yugoslav attack(only played against it once and had to play the dragondorf). I actually won that game with the dragondorf but i know that the opening is not that sound and i saw some lines that are dangerous for black. I will continue to use the dragon(against players that i know that don't use the yugoslav) but my rating is becoming higher and i will competing in more serious tournaments(national championships, etc) and i would like to try the najdorf. So i need your feedback: The dragon was quite tactic(even when not playing the yugoslav) and i would like to know if we can say the same about the najdorf? What are you opinions about the najdorf(how would you characterize the opening)?
Give me some feedback, Najdorf fanboys(girls)
