Whilst MS Maps has alternative route options and it indicates on which side of the street the address is located, that's where the benefit ends for me. I prefer the Here products, even if they are split into two (Maps and Drive+).
MS Maps has no Drive option, ie, you have to input a destination. Sometimes I like to just see where I'm driving or what the road looks like ahead whilst getting an accurate GPS speed.
Whilst driving, the MS Maps current speed is half hidden under the road speed limit (on my L950), thus unusable.
Too much of the screen real estate is taken up with upcoming directions.
When searching for an address on MS Maps, the results does not include additional info, such as suburb. Quickly locating the correct address amongst the results is a chore and takes time, even though they are numbered. There is also no quick and easy method to click on an address and go straight to that location on the map, seems like you have to keep zooming in.
The MS Maps Live Tile has no address detail on the small tile.
"Navigating" around the app is cumbersome, I keep clicking the wrong thing whilst scrolling or trying to choose something. Example, trying to see whch route is which when there are a few to choose from. The actual map dissapears whilst giving detailed directions when all I wanted is to see which route takes which time, or it chooses that actual route, or the map disappears whilst I scroll down to view the verious alternative routes. Confusing, to me at least.
There are a couple of other small points in favour of MS Maps and Here, but these are the main ones for me. I don't use Here Commute and the underlaying maps are the same.
