I'm a sucker for promotional blurb - so when I read "D'Addario NYXL strings will bend further, sing louder and stay in tune better than any guitar strings ever made" well I immediately believed them and shelled out a whopping $12 for a set. I'm also a sucker for anything with "NY" in the name. 
 
Going to restring my Tele with them tomorrow. Have I been a fool? 

I will be looking forward to a full report.

I think I'll stick to my GHS Boomers.

According to some comments I've read, they squeak less during slides. Not sure if I approve. I like my squeaks.
