You are missing a very important point: Durability to power failures. (Excuse me, but a majority of GNU/Linux users are not switched to a UPS or something.) And that's where XFS totally fails[1][2]. And considering my personal experiences, reiserfs is the fastest fs (among ext3 and xfs) in terms of boot recovery phase times. Regards.
