This is my name (female). I personally love the spelling better than other forms. I've always felt it's kind of a tomboy girl name. It's always fit me perfectly. But I will say the downside is that people ALWAYS think it's short for Jessica and almost never spell it correctly when I give it for orders (doesn't bother me because I'm used to it, but might bother others).
I have a friend with the name Jessica; she hates it however and goes by Jessi or more frequently "Sharki." Anyway, it's pretty enough, but the awful Jessi Slaughter ruined it for me. Thanks to her, this name will always mean (to me, at least) scenewhore-chav-liar.
