Whitefish or Banff for end of summer trip?

To celebrate my recent job offer, my wife and I decided to plan a couple of one-week trips before my start date at the end of August. She picks one, I pick one. We are Chicago-based. We just got back from her pick, Moab, and absolutely loved it.

​Now it's my turn, and I’m torn between Whitefish and Banff. We are looking for something similar in terms of being hiking-centric, but with a different scenic vibe than Moab. We also loved the walkability around downtown Moab, so would ideally prefer that again to wind down from our day trips to the parks and trails.

​Anyone have any advice to help me decide? I feel like there's no wrong answer, but my wife set the bar high with Moab! 😁
