Best mapping and route planning experience some other time
It does not know anything but motorways in half of Europe. Even on motorways it does not know the junctions. Google knows all junctions, most minor routes even in Easterne Europe. For example it knows about the existance of the Belgrade ring road, Sofia ring road, Budapest ring road, etc. Ovi does not. As a result I spent 2.5h crawling through a traffic jam across the Belgrade city center and wondering "Ok, the GPS is plotting the road through here, why I do not see a single truck on it". Similar (though shorter) experience in Budapest.
It is also completely lost in Holland with their bloody split motorways where instead of rebuilding bridges and widening they have built a couple of lanes in parallel with the old one. In order to take the right junction in this spaghetti you sometimes have to switch to the "correct half" a couple of miles in advance. It is totally lost there as well.
Czech maps were also clearly substandard so trying to navigate the roadworks on the work-in-progress motorway between Prague and Dresden I ended up on some mountain roads instead.
Best mapping experience? Do not think so. I analysed the same routes on Google maps and in all cases it brought better answers. Same for using a proper Garmin GPS.
