The only real difference between the two characters is that one wears a helmet and the other Weezer glasses.
Actually that would be a false one to some extent. The supporting cast of Half life makes Gordon a more believable character and likewise you see a certain character advancement by proxy.
Also overall there's a far tighter character interaction with everyone in the game. Not just Alyx, but the rebels, Barney, etc etc.
