[ND-3500AG] Best firmware to backup my XBOX 360 games?

I was wondering which is the best original/modded firmware to backup my XBOX 360 games on DVD+R DL?
At the moment I am using the 2.FC_QV3ME modded firmware, but I haven’t tried to backup games yet.

It’s quite old firmware, better use a newer one - 2.FD or official 2.1B
