THIS a x1000 THIS !! There will never be a perfect framework, and jquery for a multi-person big project. It WILL be a mess in due time ! a Framework(even the most of the crappy ones) at least give you some opinionated standard ways of doing stuff. You can't pay me enough to work in jquery straight... Not saying it can't happen with frameworks. Just saying if you do a 100 projects with jquery or 100 projects with frameworks... There will be more chance the jquery ones will be a mess.
