Half-Life 2 vs Doom3?

I'm a big fan of Half-Life including Half-Life 2. It was my first PC game back in 1998. I heard that it won over 50 game awards and made a revolution in first-person shooting games. Well, Half-Life 2 is even more fun, great storyline, stunning graphics, impressing physics engine and breath-taking sounds. Won over 30 game awards, I think. But how if compared with Doom3? Which game will you think is better? I didn't even tried the game because of it's dark gameplay and of course quite scary too.
