Get the Yamaha...
To tell you the truth, I'd rather have even the Yamaha 6416 than the 10/12/32 Que! drive.
And there is not much difference at all. If you are talking about rewrite speed, then I haven't even seen media capable of more than 4X rewrite.
Not recommended, anyway.
I have the Yamaha 8424 and I rarely ever even use 8X write.
I always do 6 for data, 4 for audio.
And anyway - there is a new Yamaha drive that is something like 16/16/40 or something
