I haven't broken a string either (I played really soft 90% of the time) but I just thought I'd replace them because my acoustic's strings were getting pretty gross and not staying in tune so I got some for my electric too.
I have a decent Ibanez that I thought felt/sounded just as good as the Gibson's when I was buying it. I'd like to compare them again since I also sucked at guitar back then. I did just go trying out some acoustic guitars when I bought strings but didn't notice a huge difference between the nice guitars and the one I have, except they looked a lot nicer. (Mine is pretty grody since I sloppily took off the pickguard and never bother cleaning it.)
@Legacy, post recording, yo.
