Well, greymatter's easier than wordpress/Movable Type to install simply because it requires no database blah blah. You upload and start off. However, it's got a really, really, really stupid configuration menu as far as actually customizing the layout, etc. Movable Type and Wordpress require a host that supports MySQL/PHP and take a little bit of work to install (not much), however, it's pretty straight forward to tool around with the layout and junk. Wordpress is free and open source, whereas Movable Type has a somewhat limited free 1 license install.
