definitely go with spinner wheels though, so much better.
Although most of our luggage is 4 wheel spinners I would say that what is better depends on preferences.
Spinner Cons:
-You lose storage space with 4 wheels
-They move around on their own easier which can be a PITA on public transportation
-They don't do as well on rough or uneven surfaces. Yes you can roll most of them on 2 wheels but the wheels tend to be smaller and have more range of motion so they will be less stable\easy to roll
-Wheels are more exposed and, therefore, more vulnerable. Plus there are 4 chances for a wheel to break instead of 2
