My experience with LG is limited. I've got an LG and a Samsung. I clearly prefer my Samsung. It has given me better burns across all types of media. I have been very disappointed with DL burns on my LG with Ritek D01 media at 4x or even 2.4x. The result is high error/failure rates and poor playback on stand-alone players. I would assume that Verbatim DL media may give a better result. However cost has kept these out reach for me. I seem to always find some closeout deal on Ritek D01 rebranded media. I don't do much with DL anyway. If I need to I use my 1693s as it provides great burns on this media.
I just thought I'd add my input. However I do realize my drives are rather old at this point and do not reflect a "current" drive. Regards, John
