Premiums are probably OEM quality (which means, good) and are made in Europe under decent quality control, with high quality materials. Made by either EBC or AP-Lockheed, both respected names in Europe (similar to Raybestos, I assume).
Econos are made...wherever...probably in 3rd world or developing Asian countries where material and process control isn't all it should be.
It's your brakes.
BTW, I just got the Premium package deal from BAT. I only have the rears on so far, and pretty low miles, but so far so good after a break-in and one autocross.
