^These two are from the final DLC. As for yuri, I'm not sure. I haven't finished my current playthrough yet so I haven't had much of a chance to learn about the characters beyond what you see in the DLC campaign.
^ I mean, I don't think I need to put "in my opinion" after every statement I say. Also, CCC being the best in the series is a popular sentiment... between the few dozens that actually played it.
^As an avid TM fan I have to cast doubt on that. CCC is fun, but far from the best in the series. I'd say even Extra itself has a far tighter plot. If you wanna go full hijinks then Hollow Ataraxia is far superior as well. In all the circles I've been to there is no such sentiment that CCC is the best. Generally the idea is that it's really great and a shame that so many people missed out on it though.
Unless by "series" you just mean the Extraverse...
^^ It's not just Homura's height that varies a lot. Her bust size seems to change from basically flat chested to a somewhat big bust depending on the medium.
^^ The DLC is not part of the main game as a full extra route but is instead an option from the main screen. It also has a separate save file from the main game and is much harder to beat than the main game.
