I like the simplicity of #4/rank 2 and the way you made the leaves into a crown. My first preference would be to make the the text stand alone as the logo without an additional icon on top, but I like the way this looks so I might consider it. I like the colors too.
Changes: Try one with more emphasis on font/text and a more integrated, possibly simpler icon. Custom fonts okay. Regarding#4 move leaves to left so the are more centered and slightly smaller. Try other fonts.
Thanks
