Similar gravity to Earth, a functioning magnetosphere, and as a bonus, there's the fact that above the cloud layer, while the air isn't breathable, you could walk around with only a breathing apparatus since the acidic stuff is heavy and not present while the temperature is pretty comfortable for humans. Even better, our breathing atmosphere would almost be as buoyant as helium, so flying cities would be possible. Given the wind speeds, people would experience day and night in 2 earth day cycles instead of... once every year or so.
