I wholeheartedly believe one is better than the other. If 'equally effective' simply means every razor blade will cut hair than yes that's true. But if 'equally effective' means every blade is equally comfortable and sharp than I do not believe that at all.
There are some Chinese blades that are horrific.
I DO think that your prep, razor and technique play a big part in each blades effectiveness and comfort level. But when you eliminate all the variables and only change the blade you will soon find out that every blade is not the same. I have done it many times.
So I guess once again...YMMV is the only winner here
+1. I agree. Technique and prep are key. However, picking the best blade for a razor makes an incredible difference IMO.
