I used to use a variety of strings, and used to go thru them like a karate man out for revenge. Think I'm a bit heavy handed... anyway
Started using Rotosound Reds (Gauge 11s) and I maintain they are the best I have tried - last a load longer than D'addarrio, Ernie Balls etc
If you're going to try a few brands and see what suits, it's definately worth giving Rotosound a go.
