Batman. Snake and Big Boss are about as stealthy as Stan's jacket. Ever notice how all of those missions are supposed to be stealth missions and the first thing they usually do in every game is get detected by the enemy? They actually kind of suck at stealth with you think about it. The gameplay may be stealth based but the characters themselves aren't particularly stealthy.
As for "Assassin Creed guy"... Which one? Not like it matters, most of Assassin's Creed is running away from guards after you've been caught stabbing somebody.
