I'm with you about everyone convincing their selves. In fact, I performed the benchmark to decide for myself which FS to choose (or more precise: which Reiser4 mkfs options were the best), but I thought I could post a summary anyway as it might be of use to other people. No need to start a religious (filesystem) war indeed; I hoped to make that point by stating in the wiki that "there is no 'one size fits all' type of filesystem"
