As I cannot post in Library section - I post it here I have a DW True Color fan (not for a long time) and my fav CMAS Winter fan, so I made some comparision shots (not very good, but I hope it'll give the idea).
I like both fans and think with some adjustment they can complete each other greatly! They're very different in their appearance on photos as TCA is on canvas and CMAS is on paper, but both are lovely. I believe if you don't know your sub-season - than CMAS can be the best choice, as it's unexpencive and suitable for all sub-seasons. Also some ladies here have found CMAS more suitable for them (as it has a blend for double-warm and double-cool). I also like that CMAS fan include several colors that I don't have in TCA fan (for me it was my skin color and my eyes color, perhaps I'll find my hair color when I'll be able to see it). CMAS contains several browns also, and several not so "bright" green and maroon. Maybe it's not that "exactly correct" colors, but they work - if you keep them clear. Ok, I'll finish with words, now pictures (not exact matches, I was in a hurry, but some ideas about color harmony in fans).
Here you cannot see the lightest CMAS fan color, as it's too many stripes for DW, but they're exist (a bit softer and deeper than TCA pallete, but I always keep in mind that they should be brighter and lighter in fabric than in paper)
