A quick search of Nexus brings up 4 different versions of this mod:

http://www.tesnexus.com/downloads/file.php?id=20575
http://www.tesnexus.com/downloads/file.php?id=4820

Reading the mod descriptions doesn't give me any clear indication of which is "best", so I'm asking here. Which version of this mod is most immersive, bug-free, not-overpowered, has the most features etc? Is one of them preferred for a Vanilla install or for OOO or FCOM?
