Phillipe was not only less attractive than Erik but the count obviously was a player. No way in hell would I give up a man like Erik. Erik loved her more than life itself. Phillipe would have been happy with any other woman. So no, Phillipe did not love Christine the way Erik did.
Sorry, I disagree with this. While I much prefer this phantom to the 2004 movie one (who was a manipulative, self-pitying, immature crybaby) and think this Erik had more empathy, maturity and probably more real love for Christine, he was still unstable, and he still wanted to control her. He had no understanding of her need for a normal life, and kept insisting she live down below with him (though he gained more understanding towards the end). He was also a killer, capable of great cruelty.
Phillipe was a ladies' man, but he and Christine had a long history. They had known and been attached to each other since childhood. Because of this, I think his love for her was real, and that he wouldn't have been happy with any other woman. We can't say he didn't love her as much as Erik did.
Now whether this version of Phillipe/Raoul would be able to stay completely faithful to Christine, even though he loved her, well, that might be a different question ;)
