Poketch vs Pokegear vs Pokenav

I loved the Poketch best of all because of how quickly you can access it. The pokegear requires time to click on it then choose your app then exit out. I was trying to catch the dogs today with the pokegear and it was annoying having to check the map then come back out every time I re-entered the route. I never really thought much about the Pokenav, though.
