This is an extended menu component hence is a little complicated for novice users. For those that know their way around Joomla, this module is very powerful. The ability to style each menu item is fantastic, as is the hide the "home" item feature.
I have deployed JCE on 5 production sites and have no complaints from users so far. I haven't come across the bugs that other reviewrs mentioned. The ability to totally customize the interface is powerful and the advanced link manager in great.
