Does it matter? Reiserfs does use a journal as well.

If the journal is allocated when creating the filesystem it probably is placed at the beginning which usually is the faster area of the disc, isn't it? Also it is contiguous, which should increase performance, too.
(why is using a swap partition better than using a swap file? similar reasons)
But i'm not an expert at all. I just dislike things that are taken for better without giving reasons to do so.

An atomic filesystem means a transaction is completed or not completed, not half completed 3/4 completed, etc. etc, To make a filesystem atomic we use logs meta-data logging as in Reiser3 or wandering logs as in Reiser4.
