I have partitions formatted with both the filesystems.

SFS is faster (only slightly faster, because it is C code compiled for PPC, while PFS3 is assembler code compiled for 68k).

PFS3 was a professional commercial product, while SFS is not (but it has been polished for MorphOS by the Team members)

Reliability is almost the same (you will have different answers according to the accidents suffered by those who reply).

PFS3 always had PFSDoctor to recover partition data, but now SFS has SFScheck and SFSDoctor (MorphOS native code).

The .DELDIR bin of PFS (where you find the most recently deleted files) truncates filenames and loses filenotes, the .recycled bin of SFS recovers these data, too.

SFS features can be controlled directly from the system settings menu of Ambient.

The main cause of hard disk trashing are browser caches. They f*** up their partition sooner or later. Create a small partition for browser caches only, and you will live (almost) quiet, both with PFS or SFS.
