Hi Daniel,
I love (obviously as it is ranked #1 :) ) entry 17. It is modern, yet medical and you can read our name below. Most reference us as EMA (rather then saying our name) so I love the acronym is large, and a modern font. Entry 19 and 15 are just a little too busy for us, and entry 15 could not be embroidered on our medical scrubs that easily.
