Structures for NO+ (Nitrosonium)

There are two possible structures for Nitrosonium :

• In the first structure, there is a +1 Formal charge on Oxygen, whereas,
• In the second structure, there is a +1 Formal charge on Nitrogen.

Q. Which is a better lewis structure?

Q. Are they resonating structures of NO+?

Wikipedia gives the first structure only, so i think that is the only correct structure.

I think structure in which less electronegative atom has a positive formal charge is better, so the first structure is better.

Q. Is the above reasoning correct?
