I'd go for the LiteOn drive. Although the LG isn't that bad, the LiteOn appears to perform equal or better in any task. The price should be about equal as well, so I think there aren't too much reasons too choose for LG.
I'm sorry I can't be very detailled about the LG, as I only know it from articles etc, but I'm very convinced that the LiteOn really is a (way) better choice.
BTW, welcome aboard!
PS: I moved this to the Recording hardware forum, seems to be the best place for this
