I would use the xmodules, as they are under active development. If there are problems, they tend to be found and addressed quickly. That said... the xmodules will probably be undergoing some major configuration changes in the very near future. These changes will greatly simplify theme settings (essentially a single class for configuration of all xmodules, as far as look/color/image/font settings go.) Currently the stuff is in beta, but it should be released soon. So... you might wish to wait a week or two and start with the new (xpaintclass) module versions - or use the beta package available now, with the understanding that some settings may change.
