Pitfall II is the best in my opinion too.
I don't know if you saw a review that: Bob "Dire 51" did about Pit 2. I agree with him also. In fact, I just registered in this site because of Pifall II. This is my first reply. I was really wishing to reply to Bob "Dire 51" but the reply button there kept sending me to another place. Do U know how? I wanted to let him know and now I am letting you know as well as everyone who reads, that because of my Love to the Pitfall 2 game, I am developing a sort of a Pitfall 3 (of course with another name because of copyright) and I would like to share the 3 areas I've created so far with you all.
You can download it here: www.aloan1.com (after clicking on the American flag, click on the video game creation thumbnail. Have fun, like I'm having everynight upon continuing with the development of this game and playing it to test it! Best regards...
