It's a fair reply, but I wouldn't have mentioned FFXIII if I was him as it somewhat disproves his claim. The DVD in 360 isn't as great for jRPG with cinematics and in FFXIII case led to higher compression and lower resolutions.
From my point of view both are pretty equally powerful (360 is not more powerful though, that's just the same spin Sony give) however PS3 does have a slight advantage for certain titles with BR capacity vs DVD (although it pays for this a bit in slightly slower read speeds).
Try to be reasonable... its easier than you think...
