Win10 NFS Client a SAMBA Killer?

We finally got the last of our recalcitrant Windows 7 users to Windows 10 thanks to MS' recent withdrawal of support from the former, so the entire enterprise now is either Ubuntu 18.04 or Windows 10.

Because Windows 10 has a NFS client, the question now is whether to ditch SAMBA in favor of NFS.

Specifically, does any reason exist to retain SAMBA now that all our Windows clients support NFS?

SMB 3.xx has a better tuned performance over "generic" TCP connectivity and has features like RDMA and multichannel support Microsoft didn't implement with "their" (actually - licensed) NFS client.
