Chase Trifecta, Capital one duo, or Citi Trifecta for travel

Hey everyone I'm 19m and I travel four times a year in the U.S. between college and home. I don't really care about hotels or luxury I just want to get the most value out of my cards. I also don't care about the airlines I usually get whatever is cheapest which usually is United, American, or Southwest. I currently have a Discover and Sam's credit card, and a 740 credit score. I'm pre-approved for most of the Chase, Capital one, and Amex starter cards. I was originally planning to go with the Chase Trifecta, but I've been watching videos and many of them talk about how it is not as strong as it used to be. Anyways given my situation what would you guys recommend I go with?
