A $100 spend on my DL amex yields 100 miles = $1.10 in rewards

A $100 spend on my Chase Sapphire Reserve yields 100 points = $1.50 in rewards.

So why do people leave money on the table using their DL and Marriott cards vs CSR (excepting bonuses or waivers)? I’d contend most people don’t think about this stuff too deeply until they try to cash in and then are too deep into it to effectively switch loyalty.
