Vim stores functions in memory, but I think it must re-read the file every time you source it (I may be wrong about that). So in theory if you were converting a lot of buffers in a loop, a function would be faster. But for one or two buffers done manually, you probably won't notice a difference.

Using a function is also a little "cleaner" but I don't know of any other differences.

Note that 2html.vim distributed with Vim is a script that you just source, either directly or via the :TOhtml command. Bram initially created this script (I maintain it now), so you're in good company if you use script files to just source.
