XFS is prone to heavy data loss if you do not have a consistent power supply and a UPS. In short, if in any case the computer shuts down abruptly, it looses a lot data, corrupting filesystem too. That is wat most people says, and also my personal experience while on Gentoo. As my UPS is totally down, on power loss i had to meet a lot file and dir entry inconsistency. So, it should be used with care.
ReiserFS module put extra overhead on CPU, (takes more CPU while deleting and saving files, i think less in reading). EXT3 which I m right using is better than both in its own way. I have been great fan of Reiserfs when it comes to performance, but i didnt practically ever compared both. I just read what people wrote on their pages. But after I found Reiserfs extra CPU load, I switched to ext3 for testing only, and still enjoying it. Reiserfs is fastest among all filesystem when it comes to read multiple files which are so smaller, less than 4kb, but thats not always met on Desktop. So, you won't find much difference. Worst side of reiserfs, do you want to see it. OK, copy a large file(movies, 700mb) and save it somewhere else(not cut paste, it only arranges the inodes and binary tree entries). And then while it copies observe the system reactivity. That is not case with the EXT3 filesystem. What do you people say?
