The actual burner is not all that important, but to answer your question, yes these burners are very good. I have a Pioneer 105/A05, and I'm able to make backups for my xbox/ps2/movies just fine.
The difference between the AO5 & AO6 is the burning speed, and the AO6 is dual format (+ & -) whereas the AO5 only burns DVD-R/RW and NOT DVD+R/RW
