If you want the latest kernel and userspace, then Arch is definitely one 
of the two best options, the other being Gentoo.  For someone who is 
used to Manjaro or CentOS, Arch will be a lot easier to adapt to than 
Gentoo however.  Both Gentoo and Arch work very well for server systems, 
and make it a lot easier to keep up to date on security patches and 
bugfixes than most of the other popular distributions.

I actually just recently tested send/recieve over the network myself 
using ssh (along the lines of 'btrfs send snapshot | ssh user@remotehost 
btrfs recieve /target'), and only about 1 out of 3 attempts actually 
worked.  At the time, I was on kernel 4.0.  I'm thinking that something 
about recieve is timing dependent, as I got lower success rates as I 
artificially increased the network latency.
