A full Windsor knot is the only proper way to tie a tie. Anything else looks unbalanced or sloppy.
And if that's what you're going for?
To me, it's possible to wear a suit and tie and not look like a suit. Who wants to be the perfectly pressed and polish business man? Where's the individuality? I love the four-in-hand and hate the full Windsor.
Suits look great, but I hate the current style. Everything is far too uniform. The only thing that looks good uniform is a tux or full evening wear with tails. I don't know why, but somehow you can retain individuality with those, so long as you don't wear one of those "tuxedos" that are now in style that are no more than a crappy suit with a satin-faced lapel. Oh man, and don't get me started on colored vests/cummerbunds/ties... The only colors that belong on a tux (except for perhaps a flower in the lapel) are black and white.
Oh man, I got off topic. Anyway, I think the full Windsor makes you look like a banker, which is not what I'd want to look like.
By the way, I'd wear a suit everyday if I could. Unfortunately the dress code here in San Diego for work is almost always "business casual" (i.e. shirt that has some sort of collar and any pants but jeans, except on Fridays when jeans are okay). Nonetheless, I wear a tie every once in a while. In fact I'm wearing one right now.
