Snake is a character pretty hard to use. But It REALLY worths It, I guarantee you that.
There are people that prefer classical characters, with more "direct damage" that Snake. Snake is totally a mindgamer character, if you use Snake, you must be using ALWAYS all the projectiles and weapons of Snake (Use grenades, C4, land mine, UpSmash [I don't remember the name of that thing ^^U] and Nikita with strategy.).
I think that Snake will be listed as low tier by many people in a future, but that will be because all of them doesn't know how to play with him.
Give him an oppotunity, if you don't like, simply, use another character not as weird as Snake.
