Butterknife - generates findViewById and then casts it for you. Can have Runtime errors if you're type in Java is inconsistent with xml.
DataBinding - remembers id -> View map as it inflates. Checks types at Compile Time. Offers much more. IDE integration is a bit of a pain sometimes. have to clean build more than I'd like.
