Chess Tutor vs Chessmaster

Which software is more comprehensive?

Which software is more enjoyable?

Which software is more effective?

Which software teaches faster?

chessmaster alone is just a (not the best) engine, a gui with some lessons attached. The lessons are OK, but not comprehensive and not very structured. It's designed for playing, and for fun. Learning is bolted on. A chess.com account and a free engine is just as good if not better.

Chess tutor is a much more progressive, comprehensive learning tool. It is designed for teaching and will be far far better at it. It probably is less enjoyable than chessmaster unless you enjoy learning, putting in the effort, and getting better.

Really, chessmaster is a chess program with some (admittedly good) lessons from Waitzkin and Pandolfini added on. Chess tutor is a structured complete  chess course with a chess engine added.

re chess tutor, I say complete, I don't know how far the steps go, it starts quite basic. but you can download free demos from their website. I've seen it, but don't have it myself. you could get the demos and compare it with chess mentor here, which is quite good, though a bit unstructured. You might prefer books. Chess seems to me to be ideally suited to computer-based learning, but most of the software I've seen hasn't been that great. And people are still publishing books, when pgn files with annotations seem to me to be much more sensible. I wonder how many people buy a book like Kasparov's predecessors books, then look at the games in chessbase?
