Recreating SC1 with mods

Hi, I know there are mods that recreate the old Starcraft1 with the sc2 editor. a i have seen some with different us and i wanted to know the difference between vbari projects, like SC Reawakening or SC Mass recall. what are the differences between these two? and are there other similar projects still active or previously cancelled? I like to make a nice comparison between these little pearls of the community.
