Those were the ones I had in mind too actually. I think it might have to do with how the other characters actively interact with eachother rather than just talking to the protagonist. Allows a lot more options and opportunities to show different sides of characters. Even after Tennis Ace's prologue/Yuuchi route, the dialogue between just Yuuichi and whoever you pick is still pretty good (although I still struggle to play any route other than Shuichi's. Guilt intensifies every time he comes on screen.)
I very much look forward to Password's development. Murder mysteries are my favorite genre and I went three days doing nothing but just playing Password.
I think Repeat also does fairly well, although it IS a bit of a mess. It's not so much consistent as much as it's funny and interesting to me. I love the concept of the wishes and what type of tragic back stories the characters have.
