if you enjoy trying blades, then i agree that there's no harm in doing what some others have suggested and trying them all. Hey, it's a hobby. Back in the days when "digital" still had to do with fingers, i knew photography hobbyists who enjoyed trying all the different high speed black and white 35mm film they could get their hands on, in combination with all the different developers they could come across. I have been to the range with people who derived great enjoyment from trying all the different types of .22lr ammo they could find. I even know of people who have dozens and dozens of yo-yo's, and who enjoy posting about the subtle difference in perceived vibe between a czech point and a yyf shutter. So i have no problem with the notion that some people may find it satisfying, somehow, to know that they sampled a hundred different types of double edged razor blades.
But if, for some reason, you don't derive any special pleasure from trying every razor blade you can find, and you simply want to zero in on one blade which will work well for you, you could probably look at the various lists of the 20 most well regarded blades, figure out which 10 or 12 are generally agreed to possess those particular qualities which you most value, then try them. Out of those 10 or 12, likely at least 2 or 3 will impress you as being truly great choices.
Buy a few hundred of the least expensive of those 2 or 3, and call it a day.
Warning: Until your technique is solid, there's little point in trying to find your ideal blade. Sort of how until your driving abilities reach a certain level, it's pointless to test drive porsche vs. Ferrari, in an effort to find the best performing sports car.
