There are many cool features features in Winter 18, however I would be listing only my favorite top picks from 589 pages of release notes. Would suggest to through this post to understand Sandbox readiness dates for Winter 18.
You can check materials of this meetup as well organized by Amit, where I shared my favorite Winter 18 feature with sample code.

Base component starts with lightning: namespace. There are many new Base components introduced like lightning:datatable , lightning:checkboxGroup , lightning:dualListbox , lightning:progressIndicator , lightning:progressBar, lightning:slider. Recently only I blogged about Read only Chevron Component with mountains of code. Even though we are using this component for last 6 months however If my project could have waited, then all I had to use is 5-6 lines of code using lightning:progressIndicator.

We can already see all standard and custom component information using https://<myDomain>.lightning.force.com/auradocs URL.
