Choose based on tone and how it feels when you play. I choose my guitar, the LP Standard on tone. But, after a while i realised that the feeling isn't that good. the neck to me is too rough. i can't slide properly and it kind of affects playing although it is minor. so, yeah. choose wisely. the SG has a light body and heavy neck while the LP has a heavy body and lighter neck... You may want to consider other guitars though
