So, in this case, 270,000 Marriott points are approximately equivalent to 100,000 SPG points. With SPG, you get 5,000 more miles, but with Marriott you get a 7 night stay. If we ignore the differences, we can say that we would need 2.7 Marriott points per SPG point in order to break even.
Just the fact that SPG awards only 2 points per dollar for stays, while Marriott awards 10 points per dollar, shows that SPG points are valued 5 times as highly as Marriott points. Or, you could look at mid-tier properties that cost around 10,000 points for a free night with SPG while similar properties cost 30,000 to 40,000 points with Marriott.
