@ltdaleadergt,
I think it's a great thread topic, but I can't answer it in the standard way. I can only view individual philosophers as nodes on a network, branches on a tree. Still, to be a sport, I'll do my best.
Rorty writes good English. He incorporates much of the best with the right tone, depth, and wit. Still, he would be nothing without his influences. This applies to most if not all of us.
Nietzsche has fire and relevance. Sometimes he makes me laugh out loud. Of course he also has certain faults, certain absurdities.
Wittgenstein's terseness in the TLP is amazing. He is brutally efficient.
Hegel is such a deep and satisfying meta-physician, and is probably my favorite over all. Like I've said a hundred times, I was turned on to his genius by Kojeve. Kojeve deserves some credit for presenting the core of it so beautifully.
If I was going to give someone a single book to turn them on to philosophy, I would give them Kojeve's lectures on Hegel, for these same lectures touch brilliantly on Parmenides, Plato, Aristotle, and Kant as well. Also upon the concept of self-consciousness and the nature of time, eternity, and concept.
