-/+R Ritek/Ridata

Whats the difference between Ritek and Ridata? Is it just another name they go by? I saw Newegg has the Ridata -R 4x 4.7 50pk on sale for $40 bucks free shipping but the +R’s for $43 and around $4 bucks shipping.
Is the Ridata +R’s better over there -R’s?
I have read that a few people say +R is better but haven’t been able to find out why it is better. It isn’t as compatible it appears.
As far as Ridata goes what is better there -R or +R?

RIDATA is manufactured and sold by RITEK. It’s one of the names RITEK uses for selling its own DVDs.
