I just got my first pack of NYXL strings, I have to say I think they actually do live up to the hype. They do sound brighter and more defined than the regular strings. I also really like the way they feel under the fingers. But are they $11 a pack good? I dunno. The reason I started buying D'Addartio strings was because they are fairly inexpensive. But they are made in NY. However I will challenge the "break resistant" claim. My high B string broke as soon as I got it up to tune. I also broke 3 unwound strings on a brand new standard set last week.
