I recommend the originals as those enhanced versions are either buggy or unfinished. Yes, but they're impressive technical achievements - disassembling a DOS game and completely rewriting its rasteriser and I/O subsystem. Anyway, even if you don't use the D3D or OpenGL versions then JJFFE is well worth using over the originals; it fixes a lot of horrible physics (and texture) bugs, and adds some very useful things like keybindings for manual control of the lateral thrusters.
