Sicilian Sveshnikov, Najdorf, Taimanov, or Kan.. Which is the best?

I like the 2. e6 Sicilians. I have done taimanov for a while. Im learning the Kan now and have pretty good success so far!

At your level it really doesn't matter. Don't get too obsessed with learning openings.

I think the Scheveningen is probably one of the easier Sicilians to learn. Not great at FM+ level but very good below that level.

I'd stay away from the Svesh. Too many positions where there is only one good move for black.
