Well I think Prestige is the better option, it cost $450 but you get $500 in points (more with AA) + $250 now and $250 in less than 2 months with any airline (in gift cards). It came with Admiral and Priority Pass + 2 free guest (the only CC with that benefit).
In the other hand, Citi Exc for $450 with no credit but with 75K AA which worth a lot if you know how to use it, same AC access but no Priority Pass. Now if you spend 40k in a year, you will get 10K EQM on AA.
