I would think the map data itself would be complete in the Beta since they are using outside sources like TOM TOM. I have a 4 lane 10 mile long road close to my house that is about 2 years old that just isn't there at all in the Apple map. I don't have a TOM TOM but I assume it is on their maps already. Maybe they just got old maps for the Beta. Hopefully.
Anyone else notice newer roads missing?
Apples new maps may be accurate and good for people who live in the hubs of America (LA, SF, Chicago, NYC, Seattle, etc) and only drive the same route from home to work everyday and once and awhile to the store, but from what I've seen Apples solution looks really bad in rural or small town areas. The screenshots of European areas look even worse.
I live relatively in the sticks in Berkshire, my estate is about 8 years old, they finished building it about 6 years old. Google Maps shows the estate only 1/4 built. Apple's maps shows the complete estate built and even the new coloured mini roundabouts that were remade about 4 months back. So here, Apple wins. most of my area looks better on apple's satellite maps than googles.
It's going to take time for Apple's maps to be perfect, but Google's did too, the only difference was that they had no real competition. street view took years to be any good. people just have no patience.
Also it could be that whilst iOS 6 is in beta, we're stuck with a limited version of maps and the full force will be flicked on when we hit launch or GM. not necessarily perfect, but part the way there, with Apple making headway on improving. Simply, this can only get better from here on out. who knows, in a year, there could be 3D for most the world and people will be saying how amazing it went from limited to decent.
As for the non-satellite maps, they definitely could do with improving with the standard for blue for motorways, etc, i would hope that would change soon
