Baby Bjorn Mini vs Ergobaby - which one?

Looking to get a better carrier for when we go out. The Baby Bjorn seems simpler but everyone says the Ergobaby is more comfortable for longer periods. We're in NYC so we'll definitely be using it for public transit and walking around a lot. My wife likes the aesthetics of the Bjorn (lol) but I'm more concerned with actual comfort for both of us. Anyone use both and have real opinions?
