They both sound very good, my personal pref is for the “after” in this case but I really don’t think there is enough difference to justify the effort IMHO, I don’t belive anyone would be able to do a blind test and know which was mastered and which wasn’t…either one is totally acceptable as a listen.
I think the comments from cmafia and sherz cover it really,
for myself I have decided to try and get it right while tracking and leave well alone (apart from the loudness thing)
