NetBSD runs on a subset of the hardware that Linux runs on, other than supporting a very small number of systems built in the 90s that have never been supported by Linux. NetBSD's portability was a strong point in the past, but the massive industry acceptance of Linux means that there are giant numbers of shipped systems that came pre-installed with Linux and which have no support in the NetBSD kernel. There's a bunch of great reasons to choose NetBSD, but comparing its hardware support to Linux isn't one of them.
