I've had weird issues with some applications and NFS on macOS (notably, Final Cut Pro X and Photoshop). And I've also had weird issues with SMB and some apps (notably, Photoshop again!).

But at least SMB has been pretty stable for years. NFS support has had some hiccups. A few 10.14 macOS releases broke NFSv3 and NFSv4 for me, but it was fixed in later releases.
