A WS monitor shows you more then you see on a 4:3, it is just smaller for the same diagonal size.
So, you're admitting that it is smaller. Good.
Now honestly, think about it. When you're looking at pron or something and you want to "inspect" it, what do you do? You click on the magnify button, right?
So while you're playing Bioshock or anything other game in Letterbox & I'm playing in 4:3, guess what, I can see more clearly because things are "closer" to me than they are for you (all things being equal & we both have 22inch monitors).
You might have a slight advantage by being able to see a bit more peripherially, but if I'm shooting from a vantage point above or below you, then you've lost that advantage. Additionally, you're a larger target on my screen, so again any advantage is lost.
