ANTLR is LR, Spirit is LL. Spirit is embedded in C++, ANTLR is a separate preprocessor.
Spirit is slow to compile and isn't very efficient at runtime, but it's fairly nice to use once you get used to it.
As for runtime performance, it depends on the use-case. http://alexott.blogspot.co.il/2010/01/boostspirit2-vs-atoi.html
