I like [name_f]Amy[/name_f] more than [name_f]Emmy[/name_f] although I might be a bit biased!
[name_f]Emmy[/name_f] to me feels like a nickname. I like it as a nickname. As a full name though I don’t like it. It feels cute for a kid but I can’t picture an adult named [name_f]Emmy[/name_f] in a professional setting.
