I've only tried EB, D'addario, Dean Markleys, and feline strings in the same gauge, but here are my thoughts. (I'm not a tone konnnasuuur (if it were gonna be spelt wrong, it were gonna be spelt wrong proper) and my amps not so great so they're mainly based on the life of the string and whether I liked the tone rather than what I thought of the EQ)
EB are below average- not atrocious, but just dissapointing in every area you care to mention, except for the first 5 minutes you play them.
I bought some DMs cos they were on offer, and although they weren't bad... they are the only brand I have ever had A string break on my Tokai. sounded nicer than the EBs, but not by a great deal.
I keep going back to D'addarios because they sound good for Ages: my hands sweat loads. I've never had one break, and I'll typically get a month of reasonable play out a set.
The Feline strings were covered in rust in 2 days... I can't understand This as I've never heard any bad said of them. I'm considering testing d'addarios, SIT, and the other brands mentioned on this page in a group test at some point, and I haven't written them off, as that isn't the norm surely?
WezV, I heard LaBella mentioned somewhere else, where do I get them? I couldn't find them (in the UK at least) when I looked.
EDIT: when I first started I used elixir for A while.... Can't remeber how they sounded, but they certainly lasted ages with no rust, but not 3 months, and they cost 3x as much as d'addarios.
