I did a search and didn't find the answer.

So I'm a Lifetime Platinum at Marriott and recently signed up for an SPG account as well as a result of the merger.

I have both credit cards.

I probably spend 100 or so nights/year on the road, typically with Marriott. I'm not enamored with Marriott any more, and in fact am staying in the Little Rock Four Points as I type this as the full-service Marriott was sold out this week (and even though the GM offered me an override, I nixed it in favor of an opportunity to check out a low-end SPG property).

My question is this: what's the fastest way for me to accumulate meaningful points (for future hotel redemptions) using either my MR or SPG card at either Marriott or Starwood properties, as I can obviously easily exchange back-and-forth for the 3:1 ratio. Is either program currently more generous than the other regarding point awards?
