Platinum is still the sweet spot, which is all I bother to shoot for. 4pm late checkout is worth the most to me, breakfast (elusive as it is these days) is appreciated.

As far as dollar amount:
Bonus points: TPG $360, and I'll concur, about $360.
4pm Late Checkout: TPG: $120, I'll say $150 given some Hilton properties will offer this for ~$40-$80, and it is a benefit I do use quite often.
Dedicated Phone Support: TPG: $20, I'll give it $0. I'm still on hold for 20+ minutes to change a reservation because Marriott's IT department is so incompetent.
Enhanced Internet: TPG: $60. Me: $0. Most hotels I stay at these days no longer have the captive portal/sign-in screens and everyone gets the same thing.
Upgrades: TPG: $1,200. Me: $400. Just looking over how rarely I get a true upgrade and the delta between what I paid and what the upgrade would have been.
Lounge Access: TPG: $150. Me: $30. I'm not paying for lounge access. My $30 is whatever I'd probably spend at a nearby bodega over the course of a year.
Welcome Gift (breakfast): TPG: $360. Me: $120. Similar to the above, even if a client is paying for the trip, I'm not going to pay for an overpriced hotel breakfast. And most of my stays are at the lower-end of the spectrum where a passable breakfast is included in the room rate.
SNAs: TPG: $200. Me: $30. I like the idea, but they often expire before I can use them, with many of the hotels I'm staying at not having any true upgrades. One of the Westins I stay at doesn't even have a suite in the entire hotel.
So: TPG: $2,475. Me: $1,090.
