Less characters means less data being transferred, but I generally
consider that to be a negligible difference. For me, I feel shorthand
can enhance readability (along with formatting of the CSS in general).
In the end, I feel the use of shorthand is mostly subjective. If it's
beneficial to you and your clients, then it's probably a good/safe
application of CSS shorthand.
