Did you try strumming lightly, one string at a time to see if there is buzz? I do this when ever I hear buzzing in my strings, only to realize it's my fault due to not fretting well and not the guitar. As I understand it, electric string gauges run different than acoustics. Of course, the other guys here can tell you more. When it comes to the electric, I find it's a lot less forgiving on clumsy fretting compared to my non-electrified acoustics.
Since I've been at this for a short time (coming up on a year in a few months actually), I save my old string packages and write on them if I liked them or not. It reminds me what gauge I used and liked/didn't like... what brand, or type also.
Art and beauty are in the eyes of the beholder.
What constitutes excellent music is in the ears of the listener.
