So I counted to see how deep in the list of preferred moves it was in classical games.
Rated 600 The move choice is Nxc6 ... Class G player, ... c4 was #7 in the list of preferred moves;
800 (Unknown) ... Class F, ... c4 was maybe #7;
1000 Nxc6 ... Class E (C5), ... #6
1200 (Unknown) ... Class D (C4), ... #6;
1400 Nc3 ... Class C (C3), ... #5;
1600 Nc3 ... Class B (C2), ... #4;
1800 Nc3 ... Class A (C1), ... #4 (I would have assumed it reaching #3 position);
2000 Nc3 ... Expert (CM), ... #2;
2200 Nc3 ... Master (NM) ... #2;
2400 Nc3 ... Grandmaster (GM) ... c4 is preferred choice #1 position, if in rapid or classical games, but not in blitz and faster time controls.
@giziti It took some time, but I was curious too. It was done manually by clicking at the ratings on the link above.
The lichess database preferred move was Nc3, but the master database was c4. I guess the master database is more GM level moves.
