DOOM + DOOM II

DOOM + DOOM II packaged id Software's classics, threw in a couple of additional settings, two OST remakes, a couple of minor improvements here and there, and some tasty, tasty mod support. All that kind of makes this the best port available right now, but it will be hard to convince anyone but diehard DOOM funs to spend any money if already in possession of this legendary FPS duo. Then again, if DOOM or DOOM II is in your library, then there's no price-tag attached.
