All of the LG BH/WH 10/12 drives use the same Renesas chipset and have been good burners. They can even be crossflashed back and forth between models, my WH10LS30 has spent time as a BH10LS30, WH12LS30, WH12LS39, and a few others :).
Starting with the WH14, LG changed to a Mediatek chipset. It is a distinctly different drive.
I recommend looking at the quality scans of the media you are most likely to use in the BH/WH10 threads and compare with those in the WH14 thread to get an idea which might be a better choice for you.
