Reset array to initial state (delete all elements)

Question

I was wondering which was the appropriate way to reset an array to initial state, and so delete all the elements that it contains.

I found the following ways:

1. delete paidPlayers;
2. paidPlayers.length = 0
3. array = new type[](0)

I understand that those are equivalent from a result point of view, however I suppose there are differences about gas usage

Solidity docs recommends using delete array

Use delete on arrays to delete all its elements.
