Hello Igor, if you have unlimited funds then the costliest 67 mm Polarizer in the world - all the great brands you list and some more - is best for you, and great news for the manufacturer as you help them keep afloat.
A Ha! you also mention "Hidden Gems". So here is one - ZOMEI from China. I bought two when they made an entry and were struggling to market them. I am quite happy as I paid peanuts then. You may want to read this review:- http://www.davidkennardphotography.com/blog/990-zomei-ir-filters-review-comparison.xhtml I suggest you buy a Zomei and try it out yourself. It wont burn a hole in your pocket. Best of all these Chinese sellers on evil bay offer free shipping. Regards.
