I certainly can't claim deep understanding of Benko positions. I find it very difficult to tell when Black has enough compensation and when he doesn't. But lately I've been dabbling with 10. Rb1 in informal games, and I haven't found that it plays itself, to put it mildly. There's still a game of chess after 10. Rb1; whether White is objectively better, I have no idea.
One simple question I have, which no doubt reveals the depths of my ignorance of this game, is how much White should strive for simplification in these Benko-type middle games. It seems to me that as long as Black has both his rooks, he can claim some compensation. So is it better for White to play a maneuvering game, or to simplify?
The whole point of the Benko is that Black usually gets a better endgame, thanks to his active rooks, and White's loose pawns. White should try to keep all his pieces, then Black's position becomes congested on the queenside, this is the whole point of 10. Rb1! But i agree with you that White's 10. Rb1 system doesn't play itself.
Anyway I used to lose alot to the Benko in blitz games... until i started playing the Benko as Black myself

Most unpleasant seems to be 4.Nf3 g6 5. cxb5 a6 6. b6, White keeps a solid position with no weaknesses and a space advantage. Palliser's lines are excellent, perhaps the strongest chapter in his book. Titled players on playchess.com normally go 4... Bb7, when i think 5. Qc2 is somewhat better than 5. a4 and Palliser's 5. Nbd2, but that's a matter of taste.
Tricky stuff like 4. cxb5 a6 5. bxa6 g6 6. Nc3 Bxa6 7. f4!?, 5. Nc3, 4. Bg5 (Stohl's recent survey in CBM is inspiring) can be dangerous, and even if Black knows his stuff White isn't worse and there's still an interesting game to be played. If you want to accept the Benko pawns i think the line with 8. Kxf1/9. Nge2/h3 (then Kg1-h2) is worth a punt having been played by Shulman many times, Shulman-Khalifman Khanty Mansiysk 2005 is a model game (see Flear's chesspub ebook), i found it useful that the knight on c3 is given protection, this also seems simpler than 10. Rb1 i think?!
