which do you prefer? i just picked up both a few days ago.
Secret origins, by far. Birthright had a good beginning and end, but the bulk of everything in between sucked. Secret origins took all the best aspects of the various origins and put them together into a cohesive story. It may have seemed redundant at times because of that, but it was done rather well.
John Byrne's Man of Steel!
John Byrne's Man of Steel!
If it's just between these two it's going to be BR.
Same with me, but again, only narrowly.
In all blunt honesty, I've never been thoroughly satisfied with ANY of the Post-Crisis print versions of Superman's origin - It's a bits-and-pieces deal with me; I like chunks of BR, but also portions of Byrne's MOS, bits of SO, etc. BR happens to have more parts that I like than some of the others.
Outside of the comics, though, my favorite Post-Crisis version overall remains STAS' pilot, "Last Son Of Krypton".
