How many of you use braided lines, and for what? Which brand do you use? What knots do you use to tie on gear?

I've thus far resisted the modern "spider-wire" stuff, but wonder if I'm missing something.

I've been a Maxima and Trilene guy for close to 30 years. I prefer Maxima, but it gets pretty pricey when you start loading up three or four rods (me and the kids). So I've tended to use trilene XT. Seems like the braided stuff would be even worse, unless it's enough better to be worth it. What do you all think?
