Alan, I have seen only anecdotal evidence against reiserfsck, and I have seen formal tests from Vitaly (which it seems a user has replicated) where our fsck did better than ext3s. Note that these tests are of the latest fsck from us: I am sure everyone understands that it takes time for an fsck to mature, and that our early fsck's were poor. I will also say the V4's fsck is more robust than V3's because we made disk format changes specifically to help fsck.
Now I am not dismissing your anecdotes as I will never dismiss data I have not seen, and it sounds like you have seen more data than most people, but I must dismiss your explanation of them.
Being able to throw away all of the tree but the leaves and twigs with extent pointers and rebuild all of it makes V4 very robust, more so than ext3. This business of inodes not moving, I don't see what the advantage is, we can lose the directory entry and rebuild just as well as ext3, probably better because we can at least figure out what directory it was in.
Vitaly can say all of this more expertly than I....
