There's nothing wrong with 16x TDK DVD+R, especially if you get spindles made in Malaysia, which are Daxon. Haven't tried the Prodisc, and RITEK F16 can burn pretty well, but it depends on the burner and batch (RITEK F16 is kind of like RICOHJPN R03, sometimes it burns awesome, and sometimes it sucks).
Also, the paper sleeves from places like Meritline and Supermediastore are usually super thin, cheap, and they suck. Get some of the nice paper or tyvek sleeves from Rima. Those are the good ones.
Here are burns from a just opened 100-pack spindle of TDK 16x DVD+R (Made in Malaysia):
