%5 versus 4.5% is $30/year if spending $6,000.
The Blue Cash $6,500 threshold is a hidden annual fee. You are earning 1% rather than the minimum you would earn with another card. In the best case you have an opportunity cost of $65 to earn an extra $30/year. This card makes no sense at your spending level.
Will Amex EDP make more sense? Based on TPG's valuations of 2cpp for MR, I will get $6000*4.5*0.02-95=$445?
