Bob:
Until recently the Pronto had more features then the RC5000 (timers and beeps) soon the new Pronto will be out and I guess it will have some of the new features the RC5000 currently has.
From what I understand, there is one team for both remotes. Philips or Marantz go to the team and ask for the features, whomever asks for them, pays for them and gets them. Some features are paid by both and are given to both remotes. When an update for one remote comes out, soon after that there is an update for the other to be able to handle the newer CCFs.
So as to who has the best features, that depends on what you find important and when you ask the question. Here is a link to the new features on the RC5000
