Query: Not even effective as no-brand polarizer

I ordered this polarizer because in some articles i have read that linears are more effective than circular polarizers.I have one "hoya circular", one "no-brand circular" polarizers as well. This tiffen did not prove its brand because unfortunately it is not even as effective as my no-brand cheap cheap circular polarizer. Comparing 3 of them i can see hoya-cir is absolutely more effective in wiping reflections.My friend has a circular tiffen, it was like the same effective as Hoya-cir. But this linear is a total dissappointment.I returned.
