DMD offers the newest features and is the easiest to get started with. So it's the beginner recommended option. GDC tends to compile the fastest/most optimized executables but lags behind the most in features.
LDC was my preferred frontend, when I coded D. It meets DMD and GDC in the middle with well optimized output code whilst being close to bleeding edge.
