Question: Cost aside, is a smaller reef tank easier to care for than a larger tank?

Infact, I am pretty sure bigger tanks are prone to more crashes more than smaller tanks.

Changes happen slower with more water volume, it's not rocket science. In a small tank, you'll notice problems quicker, whereas in a larger tank, you may not notice the problem until it builds up.
Saying bigger tanks are more prone to crashes is false. If both tanks are properly maintained, the larger tank will always be more stable.
It's that in larger tanks, people think things are ok, just because they don't see drastic changes.
That's why regular maintenance is crucial, whether your tank is big or small.
