snippets

To use small snippets of code repeatedly I always declared them as (example)

smallFlageolet = \tweak font-size -2 \flageolet

Using it like: c\smallFlageolet

but I recently found as score declaring it

#(define C#{  \tweak font-size -2 \flageolet #})

and use it as c$smallFlageolet

Would there be any technical difference or preference? (except my own, being used to the first one)
