I've been a Rotosound user for 29 years. I've tried others over the years but always go back. On a side note, the 2nd and 3rd frets of the E string on my CIJ Geddy Lee Jazz have always been a little "choked off". Not dead spots, but they did not have nearly the amount of sustain as any other fretted note on the entire neck. Not a huge deal but drove me crazy just the same. Lately, I've been on a string kick. I've re-tried Ernie Balls and for the first time, both D'Addario and DR. Not impressed with any and the fret issue remained with all. I decided to try one last string and ordered a set of the Dunlop SuperBright Nickel 45 - 105. All I can say is WOW! And lo and behold, I no longer have the issue of the choked off notes. Not sure why this is but I don't care. The sound and feel of these strings are phenomenal. I've only had one gig and I want to see how they are once they settle in. But I already feel that this will be a permanent change.
