Insufficient info, I'm afraid.

Why do you consider this app 'complex'?
How do you expect this person to work? Handed full specs? Expected to ask questions/clarify requirements themselves?

I'd be looking at their wider experience (assuming my definition of 'complex' matches yours)

Whoever convinced me they were the better developer, unless the difference was very small and one had worked on some specific technologies the other hadn't.

You've never run a real business.

The ones with the (any sized) boobies get pregnant. This is a great thing for them and their families. It is a less good thing for your company.
