oil coolers.... Areo classics vs Positech

Anyone have any experiences good or bad with either of these coolers? I
don't know which one to buy.

Areo classic 9 plate weights 2.08 lbs cost $170 from spruce

Positech #4215 weights 4.1 lbs cost $165 from vans

Both manufactures claim there product outperform other brands.
Somewhere I think there was a problem that has since been corrected
with the early models of the Positech. I'm not that interested peoples
personal opinions but rather information from users who bought and
installed these coolers.

Thanks in advance for your help
