I just hope whoever buys HERE doesn't screw it up. At the moment I do like them more than the google maps. They are also cheaper when it comes to licenses.
Samsung has been slowly building up their own "shadow stack" for mobile. They have everything from the OS up, but map data is a huge missing piece.
Also, I think Samsung's homegrown Tizen OS has some ambitions on the automobile side, and that's a market where Here has been doing well.
Even now the current HERE Maps allows you to cache full countries for offline traveling and a bunch of other small features that add-up to leaving GM in the dust. Full offline caching has saved me in a number of situations. If Apple Maps wanted to compete with GM, they should buy HERE... and rename it to something better. It's been renamed about 4 times over the last 8 years.
