Ok, but he's still better than "Im-a-hero-and-Im-only-standing-here-to-do-quest" type of main character in Fallout. Only way to actually make an opinion was in speech challanges and in a quests, where you have to decide who you'll be supporting - but not in all. You're just asking about Mojave, fractions and quests. In AP you can be sarcastic, you can joke, you can insult other NPCs and you can choose your personality. :') No harm to Fallout New Vegas, it's a different type of RPG, I'm just saying that I prefer Alpha Protocol. :')
You probably just prefer a third person voiced PC. Which is the way to go if you want to give PC an identity separate from the player.
Edit: Speaking of characters, the old crazy guy in NV was even better than Hecht in AP, so I think you could come up with equal quality counterparts in both games, although AP character tended to be more over the top, and also there were fewer of them, so some got more attention.
