With the AmEx BBP card, with $20,000 spending, the base earning is 40,000 MR points, which can be transferred to 40,000 partner miles.
How you max the SPG and get 3x? Only through Marriott/RC/SPG hotel stays. That is very limited. AmEx has a full lineup of other cards that can earn MR points, such as the Plat, PRG, EDP etc....
You're the one missing the point, the SPGB & Marriott Biz 4X categories are not at hotels at all, it's dining and gas to name two.
We're comparing old SPG to new SPG which the earning is equal for transfers.
Since you want to mix things in, using the SPGB on one of the 4x categories spending $20k would = 75k plus miles
$40k= 160k miles
$60k= 240k miles.
