Difference between HERE Maps and 'Maps' in WP 8.1

[windowsforever]

I just upgraded to WP 8.1 on my Lumia 620 and now I see 'Maps' which is a default app (can't be uninstalled) along with HERE Maps. I updated my HERE Maps and the 'Maps' app also shows that it's maps are up to date. I wanted to to know if there is any duplicity here. Can I uninstall HERE Maps? The 'Maps' app redirects to HERE Drive too so I don't see a point keeping HERE Maps if both of them are the same things.
