I use Thomastik Infeld strings. They cost a little bit more but are definitely an improvement in quality. All other brands of strings are made by one of three manufacturers worldwide so it really doesn't make any difference except for Thomastiks.
I use gauge .013-.053 on most of my guitars and .011-.050 on my Springy and Jazzmaster.
