Rossolimo 3.Bb5 vs open Sicilian against c5-Nc6 sicilian Many chess players nowadays recommend the Rossolimo against c5-Nc6 Sicilian:

[fen ""]
1. e4 c5 2. Nf3 Nc6 3. Bb5




However, I find the open sicilian to be easier to play:

[fen ""]
1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6 8. Na3 b5 9. Nd5 Be7 10. Bxf6 Bxf6 11. c4 b4 12. Nc2 a5 13. g3 O-O 14. Bg2




One of the reasons of my preference is that I have control over the d5 square and black has a backward pawn on d6. Moreover, I can play moves like Qd3,a3, and play on the queenside with my rooks too.

My issue with the Rossolimo is that it gives up the bishop pair for no obvious outpost for the knight like the second position in the open sicilian that I shared above.

I would really appreciate it if you can tell me why the Rossolimo might offer better winning chances with White, and why top players are attracted to it, and why Black players try to avoid it in their repertoire. Also, if you can refer me to good thematic games with Rossolimo.
Please note that the ...e5 push Black does on your line is not forced and there are plenty of other variations Black can opt for (like 4...e6, or 4...g6, or 4...Nf6 5.Nc3 d6, or even 4...e5)

Each of this alternatives requires White to be prepared as Black will probably know a lot of theory about those (and have a good understanding of the resulting middlegame positions, for instance, no d5 weak square in many of those) With the Rossolimo, White can opt for a quieter game where knowledge of precise lines is less relevant
