BS3 isn't bad it just has a few obnoxious block pushing puzzles.
Simon the Sorcerer 3D's actual content is good but it's an "open world" i.e. a huge empty map which makes it worse to play. (it's also meaner in tone, apparently it was made because the nearly finished 2D game that was meant to be Simon 3 couldn't get publishers for not being 3D)
Gabriel Knight 3 is also fairly interesting it just has some bad puzzles and a wonky camera.
Monkey Island 4 is downright good, it has one bad minigame near the end (Monkey Kombat) and a decent chunk of people didn't like the story direction of the carribean being turned into a tourist attraction. (or the minor retcons like herman)
KQ8 I haven't played.

They also went behind the back of Roberta a whole lot on it both in direction and content. It was the game that made her decided to retire from the post-sale Sierra because her name was on it but people kept gainsaying and ignoring her directives, Ken Williams talk about it in his Not All Fairytales book.
