On the downside, the Knight is the most out of play on this square compared to the other two choices, and in many variations it's going to get pushed to d8 (an especially poor square) or have to retreat via b8 anyway.
Nb8 - The Breyer move is a very flexible choice, on the other hand.
I ended up ditching the Sicilian because I had way too much theory to deal with with the my two defenses to 1. Eventually I ditched the Sicilian to work on the open games because I was winning a lot of games as Black against weaker players and obtained equal positions against stronger players with 1. I was quite surprised by this fact and did some updating on modern moves using chessbase.
The quality of the Breyer is almost equaled to the intuitive playability of the Nimzo-Indian... Breyer might require some intensive learning, but improvising when you forget some of the theory after move 15 tends to be more forgiving compared to some openings.
I feel much worse about forgetting the theory to the (Max Lange or that Italian/Scotch gambit complex in general) attack compared to forgetting the theory to the Breyer.: For a while I found the Breyer almost impossible to beat so I started playing it.
This opening seems to suit my positional style, as it focuses on putting pieces on their best squares, for example, the knight goes to d7, the light bishop goes to b7, the dark bishop tries to go to g7, and the rook goes to e8.
Another exicting thing is that black can play ...d5 if prepared correctly.
