I've always liked them. I bought them exclusively for many years. For me it was a tone issue, a mellow sound to accompany my singing through a small PA in a solo gig environment. The guitar was amplified through the PA, too, so balance was always under my own control and I didn't need stronger, brighter strings to balance with louder instruments. They were a little easier on the fingers and I changed them at least monthly, which was about as long as they kept a fresh tone. There's no doubt they aren't for everyone, but they have certainly served an appropriate role in some circumstances.
My 2¢.
Where's my change?
