Mad Dog MD-16x3dvd9-8x (ND-4550) DVD +R or -R?

I know this is a noobie question but I’m going blind searching this forum.

I’m picking up a Mad Dog 16x3dvd9-8x (NEC ND-4550) tomorrow at my local CC (my first DVD burner).

In terms of media has anyone determined if either DVD +R or -R work better in this drive, or is there minimal difference?

Any particular manufacturer/brands to look for or avoid would also help.

Any suggestions are appreciated! :confused:
