I've heard that SMB-fs is "better" than FUSE. More cross-platform, can also be implemented in user-space, and less likely to get jammed up/deadlocked by slow network calls inside the kernel.
I feel like 9p is a better competitor in this space, and I've actually heard of people using it (e.g. the Windows Subsystem for Linux mounts host filesystems this way and so does Crostini, the ChromeOS equivalent).
