Right now, for the annual airline credit, you have to lock in your airline selection in January. For us infrequent flyers, this is a disadvantage when we use other airlines. If the quarterly airline benefit allowed you to switch your airline selection each quarter, this would be a net positive.
Eliminating the resort credit, but adding a $200 "lifestyle and luxury" credit seems OK. The list of true resorts isn't huge, so adding brands but decreasing the value is a wash.
Adding tiered free-night earnings seems like a net positive. These FNCs can be worth $500+ in value.
I'm not a typical user though as my company travel (100+ nights per year) is allowed to be purchased on my personal Aspire card.
