All depends on the DM and the situation.
In simplistic terms, I can "teleport" from NY to LA, but that doesn't let me (A) notice the traffic jam in Memphis or (B) warn anyone who might care about it.
If I wanted someone to assess the forces of a castle I had never seen, or an enemies' battle force several miles away Overland Flight is the way to go. You can yelp about alternative methods, but Overland Flight is the easiest solution. An invisible night-time flying scout is about as good as it gets.
Likewise, teleport doesn't let me drag a rope across a river or up a tower. It doesn't let me track a dragon in flight or spray my enemies from above with a Fireball Wand. The top of a cloud-covered mountain scorns the Teleportable Wizard. "I dare you to pick a safe spot!" A smart DM will recognize the strengths and limits of any spell and create an engaging challenge, accordingly.
Just my 2cts.
