LDW-401S vs. Sony DWU-14A (Linux)

Besides the fact that DWU14A has 8 meg buffer and the Lite-on has only 2 meg and that Sony’s drive does also DVD-RW/R which I don’t think I will use;
Does anyone have any (hands-on) experience with these drives and can offer a comparison?

Also, any pros and cons on how these drives perform under Linux and how much support has Sony / Lite-on for Linux?

Do any other DVD+RW manufacturers have better support for Linux?
