Not all blades are the same - I bought a sample pack when I first started using double edged razors 12 years ago - 9/10 of the brands were horrible. Eventually I found the feather double platinum to be great, ordered a large amount from a Thai seller on Amazon because otherwise they were expensive. Also I’d say the razor burn and nicks are all down to technique, and perhaps skin/hair type. For me, even from the get go, the old school safety razors did not cause razor burn while the 3 to 5 bladed monstrosities always did because they results in a far to close shave.
