I am a Coach girl. They are easier to find near me. I have a MK bag that I love. The quality is great, it is well designed, and has more pockets than any of my Coach bags. I don't like the trend lately of MK to have huge logos on everything, but it seems the newer items have smaller logos. I hate the smell of MK stores and the pushiness of the SAs. Where I live, I still see more Coach because we have an outlet nearby, but no MK outlet. I think the collections of Coach for the last few years have been more elevated than anything from standard Michael Kors, not Michael Kors collection, which I never see anywhere.
I haven't purchased a new bag (that I've kept) from either designer in the last 2 years.
