I've always used both SFS and PFS partitions.. but SFS in serious use and PFS on temp and test partitions.
And always when I try to use PFS(3) seriously, I find a new bug...
For example in ftp-server use... pfs3 flipped completely. And then with fast machine.. deleting several dvd images at once, pfs went broken. Then I heard from other users, that you shouldn't delete many big files at once.. what kind of fs it that??
Sooo.. SFS has worked much better here.. and it feels also faster in real use IMHO.
Only bad thing in SFS is fragmenting, but you can avoid it by not downloading many big files at once etc. And remember to keep .recycled clean to avoid slowness in low space situations.
AMC258: first symptom of deleting too many big files at once was .deldir stopped working...
