1) FreeBSD

Yes of course, we *know* that FreeBSD isn't Linux, but aside from using a different kernel (a big aside of course), there are a lot of common areas between modern BSD and Linux.

With FreeBSD 10.3 in fact Linux compatibility is a key area of improvement. According to the FreeBSD 10.3 release notes:

The Linux compatibility layer has been substantially improved and now is capable of running 64-bit applications on amd64 (x86_64), 1:1 threading, VDSO and subset of the epoll(7) family sufficient for the majority of programs.

2) PC-BSD 10.3

FreeBSD is mostly targeted at servers, but when it comes to the desktop, PC-BSD provides a more optimized desktop experience. The new PC-BSD 10.3 update is based on the core FreeBSD 10.3 update, providing numerous bug fixes and incremental updates:

PC-BSD 10.3 notable Changes

* FreeBSD 10.3-RELEASE base system
* Using FreeBSD boot-loader for install media, will be used for installed system in 11.0 as well
* Updated Qt tool-chain to support Qt 5.5.X

CoreOS is a very fast moving Linux distribution that is optimized for container delivery, and has  three main release tracks: Stable, Beta and Alpha. The most recent Alpha release represents the leading edge of development and including the Linux 4.5.0 kernel, Docker 1.10.3 and rkt 1.2.1.
