I personally like the second 'fic better than the first. In trying to cover the entire team, you gloss over a lot of details that I would have really loved to read. Medic's flashbacks in particular need a lot more elaboration. Canon!Medic is not characterized as a man hiding deep guilt at all, so you have to work extra hard in convincing me that this is the case. Sure, just giving us "Dachau" obviously brings up some very unpleasant imagery, but not everyone who lived through that is wracked with survivor's guilt. Just telling us "Medic did Very Bad Things in the War, and now he feels Very Bad about it" isn't enough.
