I've had such unpleasant experiences with ReiserFS in the past that I decided that I'll never use it again. A couple of days ago, I had a nasty power failure and when I rebooted my box, the root fs (which was ReiserFS) had mount problems. I had to fsck it with the rebuild tree option in order to be able to successfully mount it. This happened twice in a row. My friends and I also had the same experience several years back.
I'll stick with ext3 for most of the time, except for storing large files for which I use JFS.
