Ernie Ball is the best guitar string brand I've ever used.
I find .010's a bit lightweight for my liking; I prefer .011's for my high E string and .042's for low E. I've had had .047's for low E before, but I think the lighter one is a better all rounder.
I've no idea what the other numbers mean. I used to just buy the same strings all the time after finding ones I liked.
