Depends really on how much care was put into the application structure, mostly from the outset.

I've followed opinionated styleguides closely on some projects, and have also walked into other swamp projects that snowballed into something massive from a few snippets of jQuery. The difference between working on something that was intended to be maintainable from the start and something that evolved haphazardly is of course like night and day.

I still think it's more the people and approach than the tools.
