For Chanel Liberte v Misia: Liberte is more milky and less shimmery but more pigmented while Misia is brighter more vibrant and has a sheerer shimmery texture with more red.
For those wondering whether I prefer Chanel's Miami Peach or Orange Fizz: right now the vote goes to Miami Peach. Do note that Miami Peach is less pigmented with a slight jelly-like finish. The gold shimmer is very fine and not very noticeable. Orange Fizz is clearly more orange and has that amazing rich smooth opaque coverage Chanel is well known for these days, it may be harder to pull off on all skintones.
Hope this helps some!
