SICP and HtDP have different audiences. HtDP was designed for people who know nothing about computer programming, particularly students who would not be pursuing a degree in computer science. SICP was used in a first CS course. Because they both use Scheme, they're complimentary. If you are starting out trying programming for the first time, then HtDP will certainly be a better choice. When you finish it, you should proceed to read SICP, followed by Concepts, Techniques, and Models of Computer Programming.
