Help with media brands

I saw Fuji dvd-r on sale at bestbuy. Are these a good brand? The disks I saw are all 8x burning speed max. I haven’t seen disks with a higher burning speed. I have also seen the maxwell and memorex disks but I don’t understand how to distinguish between the good and bad ones Which is the better buy, dvd-r or dvd+r?

If it says made in japan on the box then get the FUJI’s in that case there made by Taiyo Yuden and there good media.
