The 4th round game 3 of Alekseev - Aronian show a good example of ending with two bishops against two knights ending. Modern players prefer the two bishops for the very good reason that they tend to win games. Usually the two bishop are better in more positions than not. This is because the main disadvantage of the lone bishop, its inability to control squares of a particular colour is nullified by the presence of the other one. This factor makes the two bishop so strong in open position!

However, the side with the two bishops have to be carefull to avoid exchanging one of his bishop because the endgame of knight against bishop is totally different. The lone bishop will having certain problem because it's path is limited to only the squares of his colour.

In blocked positions, the knights can offer tough resistance especially if they have unchallenge anchor squares. The knights can even be superior in blocked positions where they have outposts and the bishop's scope is limited.
