My favorites:
Song A
Sample 2 - Better soundstage and transparency
Sample 3 - Better balance and overall creamy delivery which I like
Sample 1 - Not bad sound at all, but overall more harsh and likely fatiguing to listen to for a long time.
Song B
A little harder to evaluate this one because the volume of sample three is higher than the other two, but
Sample 3 - I find the my preference in mics is largely biased by how authentic I feel the drum beats are. That percussive sound seems to be one of the harder ones for mics to really accurately reproduce...and to my ears most mics produce a harsher more brittle end result than what I hear live. Anyway, for this song, which I much more drum heavy than Song A, I prefer Sample 3 for the above stated reasons.
Sample 2 - Similar to Song A, good balance and overall delivery.
Sample 1 - Again, not bad sound, but overall balance is not there and the various frequencies/intruments aren't as distiguishable from each other in this as in Sample 2 especially (which has I think the best overall balance and soundstage), but also Sample 3.
