Ruby on Rails or PHP ?
ErrantX: My personal preference is the KohanaPHP (kohanaphp.com) framework. It's a PHP5 dependant MVC framewor with lots of libraries / helpers and reasonably good documentation.When V3 comes out later this year it should compete easily with RoR in terms of speed versatility and so forth (from what I have seen)Ultimately it depends on what your doing: I have prototyped fairly complex sites with ease in a day using Kohana. Im told RoR is pretty good at that too.I usually recommend PHP for big projects - but I suspect that is because I have barely touched RoR and so am biased :)
