Hopefully when 2.0 gets out of beta, it'll be less confusing when the majority settle on it, so we can design levels without having to worry about what other people are using.
You forgot about 184.108.40.206 (Normal Lunalua).
As for what version you should use, I would say 220.127.116.11 for the best compatibility, 18.104.22.168 for less compatibility but more features, 2.0 for the most features at the cost of some things like multiplayer (currently doesn't work with new characters) and certain lua functions, and finally 1.4.x if you prefer the physics engine or do not want to use lunalua to achieve what can be used in that version.
