Not a FreeBSD expert, but consider just mobile phone patches to Linux (largely due to Android AFAIK). In this respect, Linux wins by a mile in terms of functionality (power management) and supported architectures, and I'm sure it also contributes to the perceived messiness. Another example: FreeBSD has had jails for a long time, but I believe it didn't acquire the equivalent of cgroups until very recently. Linux has a LOT of stuff that only a few people use.
