Canned cubed tomatoes vs crushed
In a chili application, the recipe is going to be forgiving.

You will get a little more texture from the cubed (diced) tomatoes assuming that your recipe doesn't then cook them down a considerable time; more absolute quantity of tomato flavor from the crushed simply because you have more of it.  Both should give you good outcomes.

Choose the one that you think you will prefer, and don't worry.
