I started off with EB slinky strings and jumped on the NYXL hype bus a few years ago. They sound a bit different, feel a bit different, but are they worth nearly twice the price of EB? ..Nope. I now use either EB or NYXL (don't like XLs) depending on mood, guitar and pickup - I've just bought a set of Cobalt's to try and will use them next time I restring. I play at home and restring probably every 4-6 weeks depending on how often I use a particular guitar and how the strings feel. I don't use fast fret or anything, just play with clean hands.
