I love D3, have been using it on and off for years. The biggest pain point I have coming back to it - esp after a release or two - are the scope of the changes!! Many methods and properties have changed thus most of the examples, blog posts, and stackoverflow assistance are outdated so it generally takes much longer than I had hoped - but the results are always worth it.
