ernie balls rust too fast for me to really enjoy them, about 1 week for me..
d'addarios are just fret killers, slightly bright sounding and they dont really last that long either, 3 weeks to 4 tops.
ehx strings aren't bad either, similar to the daddarios(i think, long time since i used daddarios) but definitely dont kill frets that fast. and they retain their tone longer than daddarios. warmer than daddarios but less than the ghs EJs.
the GHS eric johnson set i use most of the time are the best for me. warm sounding (pure nickel FTW!), fret-friendly, retains tone for REAL long. only downside is that it gets really dirty with all the grime and crap.
i use 11-52 btw, meant for downtuning but i play in std.
but the ehx and daddarios only come in 11-48 i believe and the 6th string for those are really too loose.
