Should players see maps of locations they are in?

I am currently DM’ing Storm King’s Thunder. The book contains many maps, and each of them has a DM version and a player version. I am wondering if other DMs/GMs show their players these maps. For example, an overhead map of a town. I am split on this. On the one hand, I know my players would like to see it, and it would probably help them in many ways. But on the other, I am thinking that the player’s characters would not have an overhead map of the town. So, to me, it makes sense to not give the map to the players. Any thoughts on this?
