I love CoM but totally recognize that they have made some great progress regarding the way they introduce their concepts and present the game. LitM is very much clearer indeed. And I think too that it came from the previous experience. They learnt a lot.
BTW, it is rather a mix of PbtA and Lady Blackbird (but there's some transitivity playing, here, obviously, between Fate and Lady Blackbird).
Tag management is the most talked about issue, but I've never had any trouble on this department, personnally. It's just a state of mind, IMO. With a game like that, nobody's here to win, nobody's here to min/max. Everybody's perfectly happy with failures, weaknesses and evolution through hardships.
