The whole flame war between the two is worth a read [1], at least for historical reasons; very different points of view. And while Linus disagreed with Tanenbaum's POV, I Tanenbaum's criticism to Linux made it actually better.
My favorite thing about that whole thread is the unanimous consensus among everyone involved that we will all be running GNU/Hurd in 2 years so these stopgap OSes are just academic hobbies.
