Updated support case 00912134 that Sri opened on this with:
There are no drawbacks to either approaches except in (1), there are more files to maintain/move around while in (2), there are less.
To confirm, I just tested your use case in my lab and both produces the same results when I test MW replication. So you can go with either style of setup and it will be the same. Hope this helps to make the decision process little easy as to which approach you want to pursue.
