Many users have reported the breakage of the game because of the use of the Vortex, it's not intuitive and installs some of the mods wrongly. So I consider not recommending the tool that can break the game of the end-user, Mod Organizer doesn't have any of these problems and is completely safe.
LOOT just doesn't sort the game load order correctly. For New Vegas, the load order should be sorted manually by looking through the conflicts in FNVEdit or by looking in the description of the mods you installing. Sorting the load order through the LOOT can cause problems because of the wrong load order.
