Its all about personal preference i think. They are both have similar points when it comes to stealth, some original for both sides. I personally prefer SC, especially Chaos Theory. I havent tried out double agent yet though.
MGS is fun in the sense of a better storyline, but i dont think the stealth element in MGS is as crucial to the gameplay as in SC. In fact i always felt the stealth element in MGS was very much water down, when you compare it to SC.
Example: in MGS you pretty much have to stay out of the guys line of sight, wait for him to turn his back and move. SC sometimes you cant do that, and have to rely on lighting situation and other tactics of getting around guards. This is especially important in missions where you cant off guys.
Though if your looking for quicker fast paced action, MGS is where to go. I do admit i loved being able to sneak behind a guard and stick him up. that was always a cool feature.








). No but seriously I think people don't ever give the Splinter Cell series the credit it deserves. It was the first REAL stealth game and sadly the sales are never as good as they should be.
