Which sicilian is best for you depends mostly on your playstyle. The main dragon rewards strong prep. All the dragons do... black has a superior pawn structure long term, and a very good attack on the queenside due to the bishop and the minority attack, but surviving long enough against whites testing lines to reach the endgame is key and requires precision. Dragon is good against the anti-sicilians (2... d6 always is), which is a major plus for it. But the Yugoslav attack is quite challenging, and you need to prepare that line very deeply to not get blown off the board. Personally I would choose the Accelerated Dragon if I wanted a dragon.
Hyperaccelerated dragon is interesting and it does avoid the Rossolimo, but it forces you to face some sharper lines including a stronger alapin and a difficult early endgame. The alapin is too boring, and the early endgame just makes it too easy for your opponent to get an advantageous position, so I would go with the Accelerated dragon.
There's an argument to be made for the regular dragon given that you *seriously* prep for the Yugoslav attack. Because it does deal with the anti-sicilians very well, along with just about everything else. And you will get alot of anti-sicilians for a while. At below masters level black is actually scoring well in the Yugoslav, due to superior prep.
