I love both game series, but Ace Attorney has multiple moments where you lose by presenting evidence too early or the "wrong" piece of evidence (even though it would also prove your case). The later games are better but even the Great Ace Attorney has instances of this.

Professor Layton almost all the way through includes trick puzzles which have non obvious answers as well.

Obviously the games aren't perfectly obvious and later games are much better, but they are generally much more obvious than something like King's Quest which was properly brutal. I remember needing occasional hints to manage monkey island but nothing like completing King's Quest where I had to constantly check the walkthrough.
