I don't know about the Chase but I do know the US Bank one just does a statement credit for the travel credits. Which is nice because you don't have to worry about who you are using or a process to get the credits or anything.
@Slapdashif I was doing one big trip, like Taipei, I might move ahead one the US Bank card (or one of the others after careful comparison). Use the card for all the tickets etc so you chew up the $325 credit right there. Hit the $4,500 spending in 90 days to get the bonus points ($750 in points). Use the $100 credit for the TSA world thing to make that easier. And then all the other perks for the trip. After the trip- I would consider keeping it or closing it. That's my thinking
