But some of them are most obviously not Stirling Castle. Google finds it straight away, apple forces you to look through 10 pins to find the right one.
As an example, one of the pins is "Funtastico Bouncy Castles", this would have made my school trips to Stirling castle a lot more enjoyable, but I have no recollection of the castle being even slightly bouncy.
Not unlike Google.
In my case I searched for The Ohio State University School of Dentistry. Google calls it The Ohio State University College Of Dentistry, Columbus, OH and pulls up 9 locations. 1 was the School HQ that I was looking for, 8 others were related offices, etc.. iPhone Maps pulled up 3 locations, 1 was the HQ, 1 was the Veterinary School (Shared offices in this location) and the other was OSU's dental clinic on campus. For kicks I tried my favorite GPS Motion X and surprisingly it didn't find it at all correctly.
IMO Apple maps did the best. Key learning, if you are searching any location by name it's only wise to cross check addresses. I travel a 5 state region by car regularly with a built in Navi in my car and I still live by Motion X. However, I am intrigued by the new Maps Application.
