Is JFS a good file system?

I was wondering if JFS is a decent file system. I have successfully installed MDK 9.1, and I decided to use JFS instead of ext3. I have noticed that boottime is indeed faster, but I was sondering if it is a better file system than Ext3 or RieserFS. I know they are all journalized file systems, and Ext3 is just Ext2 with jounalising capabilities, and RieserFS was wrote from scratch asd is completly GPL, and that JFS used to be IBM's propietary file system for thier Unix brand, but how does JFS rate in comparison to RieserFS as far as performance and reliability are concerned?

Reiser4 is the fastest but still beta, reiserfs is quite good. XFS is good but gets corrupted (my experience), I haven't tried JFS but I think ext3 is the best.

You can't go wrong with ext3. It's journaling is slightly more complete than ReiserFS, though it takes up more space (because it backs up file data, not just meta-data).
JFS is very fast at recovery (maybe faster than ReiserFS, but trivial). Both JFS and ReiserFS are atomic - they do not half-write to the journal nor half-recover (no inconsistencies). I would assume ReiserFS is faster in atomic transactions than JFS.
Ext3 is perfectly fine for a desktop. There is a large body of support, there is a full data journal, and performance is just fine.

Thank you for your input. After reading, I think I will stick with JFS. It just seems faster than Ext3 did when I had it installed earler.
