The white top discs look better, in my opinion. Hub printable is nice, since you get a nice even print all the way to the hub, although ocassionally the colors on the hub portion are slightly off (depending on the brand.) I too recommend Verbatim or Taiyo Yuden inkjet printables. The Verbatim inkjets that I've found have all been made in Singapore and very good quality.
I use an Epson R300 with good results.
