It's down to personal preference. I think Headhunter is pretty great, but maybe you should wait for the new Warring Kingdoms one, as it seems to be good as well.
The French Maid one looks very good as well as the one that will get out soon (warrior kingdom), but you should take a look at the in-game on Youtube. It got to please you, not everyone else ;)
jk i like snow bunny and leopard the most atm. used to like headhunter a lot, and im looking forward to the new warring kingdoms one
