I can't help but think that this is another antennagate... a problem that has been way overblown by the media and a minority of users due to it being scrutinized to death. Although I can't speak for the rest of the world, in the NJ/NYC area, the new maps is more detailed, provides more useful info and is far easier to read than the previous maps app. And my co-workers and friends who've upgraded to iOS 6 prefer the new maps as well.
As for missing features, personally, I hope Apple doesn't waste time & resources on creating its own version of Street View, which has limited usefulness for most people and quickly becomes outdated in major cities, but I do hope they eventually integrate transit info and focus on bringing more meaningful improvements than nice to haves and cool tech demos like flyover and street view.
