Just Made Platinum (from Gold), best perks?

I have been gold elite for a few years, have loved the lounge access and occasional upgrades at times. Successfully the completed the taste of Platinum challenge, what are your thoughts on the best perks as a Platinum?

Primarily travel from leisure with my wife, I'd say mainly Marriotts, Courtyards, and SpringHills, occasionally Renaissances and Fairfields.
