I've found D'addarios to be abit 'hard' though..compared to a set of Ernie Ball Regular Slinkies (both .10-.46) the EBs are alot nicer to bend compared to the D'addarios, especially right after a string change! Maybe its just me though
I use Ernie Balls and D'addarios almost exclusively, though I also use Dean Markleys and Everlys every now and then. The brand I'd avoid is GHS because I used to use them and they were very disappointing. They sounded good but broke too easily. Don't have that problem with Ernie Balls and D'addarios. Feel-wise, the best for me is Everlys, but they're a little on the expensive side for regular re-stringing. ($11 per pack)
I find D'addarios easier to bend, actually, especially their Nickelwound steel 10s. But for acoustic guitar I lean more towards D'addario. Either way Ernie Ball and D'addario get my vote.
