Reiser version 3.x is rock stable for me and has been used by many people for years. I have used it since 2002, and it was already "old" back then.
Reiser version 4.x is still developmental and I would not recommend it at this time.
In addition to stability, Reiser version 3.x is faster than EXT3. In addition to regular read and write speed, you can unplug your Reiserfs computer (while it is still active) and reboot with a stable filesystem and a quick journal recovery.
The main advantage of EXT3 is that it is backwards compatible with EXT2 filesystem tools so it can be read by third party tools in other operating systems or rescue disks.
