BlitzPlus offers DirectX 2D, Win API, sound and networking in a fairly closed package.
BlitzMax is module based, which means that altho currently it only offers OpenGL 2D, sound and some basic networking, it will eventually offer modules for 3D (OpenGL and DirectX), physics, Win API, advanced sound (thru FMOD), and probably many more not yet thought of.
Also, the languages are fairly different, not least because BlitzMax is OO (object oriented).
