I think currently the Najdorf, Sveshnikov and Taimanov are the most popular variations in top GM play these days.
The Svesnkov is unlike most Sicilian variations in that Black sometimes a base, but lots of theory.
Sveshnikov/Kalashnikov: Great piece activity but poor structure.
I have also played a lot of Open Sicilians for white. As black I normally play 1...e5, but I would also like to be able to play the Sicilian, especially against lower rated players. I have noticed that quite a few GMs and strong GMs will often tend to play 1...e5 against their peers and 1...c5 against lower rated players, presumably because they feel it is easier to play for a win with the Sicilian.
So I've started to play a few Sicilians on RHP, and this is my take for what it's worth (also based on my experience on the white side):
The Dragon is in some ways a very appealing option. I do like thematic openings (eg Marshall Attack), but the problem is I simply don't believe in it! There's also a tremendous amount of critical theory, so it's hardly suitable as an occasional weapon. I could easily find myself getting hacked by a lower rated player (especially OTB). As for the Accelerated Dragon, it's quite playable I'm sure, but I find the Maroczy Bind not really to my taste for either side. It's difficult for white to break down without taking excessive risks, but if white just sits on the position, it's difficult for black to achieve much.
As a 1...e5 player, the Sveshnikov and Kalashnikov have a lot of appeal. You just delay e5 a few moves! The Sveshnikov has of course become extremely popular, and there's again a whole lot of theory to learn. The Kalashnikov seems easier to play in this respect, but my experience here (and to an extent also with the Sveshnikov) is that I've reached perfectly OK positions with black but find it very difficult to make progress in the main lines when white just wishes to hold the position.
The Kan and Taimanov Sicilians simply don't suit my style - they're not active enough for my liking - though the Scheveningen has more appeal. But one has to be well prepared for the Keres Attack, so I might prefer the option of trying to reach Scheveningen position through a Najdorf move order. In fact I've come to the conclusion that the Najdorf (with or without Scheveningen transpositions) would probably be the best Sicilian for me, but again there's a tremendous amount of theory to master (for what would not be my main weapon against 1.e4). I have to admit I haven't tried the Classical Sicilan yet. Maybe I should give that a go too...?
