IntelliCode does give a better UX/feature set than what was ever in previous Visual Studio versions, however. The IntelliCode suggestions have a star icon to make it clearer why they bubbled to the top. The Visual Studio version of IntelliCode supports manually training the suggestions for C# (and soon other languages, if I recall) on personal/corporate/private projects and sharing the subsequent AI/usage models with team members. That ability to get all of a team on a similar model for usage/context-aware suggestions alone will be a big deal for some projects.

(Also, it's built on "AI" techniques like convolutional neural networks rather than pure usage statistics databases, so the performance characteristics are also much better than the past Visual Studio usage databases, especially on machines where it can hardware accelerate it, which supposedly on Windows 10 is most GPUs these days.)
