Lua is a dramatically different coding experience than basic wikitext templates, and resembles a more 'traditional' programming syntax (Lua being based on C) and thus offers two key advantages. First and foremost is that logical functionality – if, else, and while statements along with arrays and variable definition for instance - is built in to the Lua language, making the implementation of basic logic much easier in Lua than the hacky way MediaWiki adds it through extra add-ons and parser functions. Secondly, because Lua is streamlined for logical operations, it is much more technically efficient.
