Do you know this from experience, or just guessing?
I thought "hype" at first too, but bought some to find out. They are legit, not hype. I don't like that they use "Extreme" to describe all their products, but otherwise they do live up to expectations.
In my case, it's the 90gr Defender in a 9mm +P+ load at 1525 fps from a G19; they really do work. Penetration through both soft and hard stuff is equal or better than any JHP I've tested (most of them) over the years, and they do plenty of damage.
The damage, in test media at least, does not seem as large as the initial wound channel with conventional hollow points in my experience, but is carried a lot deeper. They also retain their effectiveness when fired through sheet metal and aluminum plate. This round penetrates 1/4" 6061 aluminum plate easily, while 9mm FMJ and a number of commercial defense loads do not.
