Regulations limited the high rates they previously could charge mean their best customers lose some benefits. The world is all about trade offsChase still has it. Citi dropped virtually everything and is worthless now.
The benefit on cards I miss the most was the 90 day price protection - I used to be able to buy stuff pre-black friday and just price match later. Or if I needed something in a rush it was a relief to know I could get reimbursed. Probably saved $300+ in price matches over a few years.
