DVD Media, Which is better for PS2 Backups? -R or +R

[jackng]

Hi,

I kinda of notice most people are using the -R media for your backups, I was wondering since the V9 supports both -/+ R which would be a better quality backup?

I'm currently using TDK 4X DVD-R media, but I'm thinking of using a +R one.

Cheers
