Here is my update since November 2022. Italicized properties are new since my last update, and underlined properties were major gems for me.

By the end of 2021, I had 67 unique Marriott properties underneath my metaphorical belt, and by the end of 2022, I have 189 unique Marriott properties stayed at (not counting Ren LHR as that is a 2023 stay), which means I visited 122 new-to-me Marriott properties this past year - wow!
