i need to know which is more capable when it comes to writing scripts.
In terms of capability, probably any script language will be adequate.
However to get questions answered quickly, I would choose Lua. There are some special features offered by MUSHclient which are only available to Lua (for example, getting style runs in a trigger.
Some of the frequent posters here use Lua these days, so you are more likely to get a quick response to a question if your script language is Lua.
Also, help for Lua is built into the MUSHclient help file, whereas help for other languages is in their separate help files.
