The thing with 8 way on Switch is that if you are on diagonal, then right/left is prioritised over the up/down. This can be an advantage and a disadvantage. If you are moving up or down a ladder and are on the diagonal, you'll move left or right when you get to the bottom/top of the ladder and might end up running in an unintended direction. The advantage is that if you are going up or down a ladder and are on the diagonal you'll instantly start running left or right as soon as you hit the ladder exit point. So long as you are planning for that then it can make things quicker/smoother. Should be less of a problem with a traditional 8 way joystick than with the Switch's joy cons though as the joy cons seem to register the diagonal as soon as you are slightly off centre with the up/down pointing, so it can be quite annoying.
