I use NFS for filesharing between all wired systems at home.
Samba is only used for MS Windows and laptops.

Few things I always make sure are valid:
- One partition per NFS share
- No NFS share is mounted below another one
- I set the version to 3 on the clients
- I use LDAP for the user accounts to ensure the UIDs and GIDs are consistent.

NFS4 requires all the exports to be under a single foldertree.

I haven't had any issues in the past 7+ years with this and in the past 5+ years I had portage, distfiles and packages shared.
/etc/portage is symlinked to a NFS share as well, allowing me to create binary packages on a single host (inside a chroot) which are then used to update the different machines.

If anyone wants a more detailed description of my setup. Let me know and I will try to write something up.

Kind regards

Joost
