I read eveywhere this polarizer is better than this one , however all opinions are subjective and didn't find any objective testing so depending on what polarizers are  considered good or bad ? aside the obvious for flare or thickness (vingetting)
After my  Hoya pro 1 was shattered , my B+W polarizer gives warmer tones but never tested them in the same scene...
