Ain't no such of a thing as "better". Your gold might me be my garbage; that's the nature of things.
Reds and Crystals (AKA "Blues") are both made in Israel. They are different from each other. But they are both popular choices in DE Land.
The two are considered to be superior middle-of-the-road products. My housemate is devoted to the Reds and I have a gross of the Blues. Smooth, sharp, good for at least four shaves in many cases, you prolly can't go wrong with either. Unless you don't like them at all.
I used the crystals for about 4 years exclusively until I came back to B&B after a hiatus. I then ordered a bunch of reds and for my skin they are superior. I used to get nicks from the get go with the crystals, not so with the reds so for me they're the better choice,
It all depends on your face since every one of us has our own skin and beard pattern and toughness. I had a uncle who beard was so thick big and tough he used a DE blade per a shave. I have been using Reds and love them.
And we still have blades manufactured on five continents to choose from. There are plenty of physical variables and then personal taste involved in shaving with DEs but the odds are that out of, say, a dozen samples, most of us will find at least three we like.
between those two, I give the edge to the Crystal blades personally. I like the personnas, just a little too, I dunno, not able to hack all my whiskers as good, way too much touch up I guess. They are super smooth though.
