Which compiler should I use?

If you're a beginner DMD is the recommended choice, as it is the implementation closest to the D Language Specification. Otherwise it depends on what you need, what platforms you intend to develop for, and your personal preferences. GDC and LDC both generate substantially faster binaries than DMD.
