Lite-On 20A3 or 20A1/20A4 family best in SATA?

I want to buy a new Lite-On SATA burner, but am trying to decide between 20A3 and 20A1/20A4 (which I understand are cross flashable). With Wind’s work on the 20A3 series, better f/w should be available. But a review of scans appears to give an edge to the 20A4 with newest f/w.

I’m leaning toward the 20A1 that I would flash to 20A4. Any thoughts on whether that would be the best way to go or not? :confused:

Thanks for your help.
