Cancelled my card today. Too annoying to use the $25/month dining credit (they are clearly trying to "trick" you into using the card as your daily driver.. no thanks) and the 85K free night award is too tough to optimize to get close to the card value.
I agree with the posters above. If you already have lifetime platinum elite status and priority pass/lounge access from other cards, the card just doesn't make sense. The 25 night boost may be helpful to get choice awards but it doesn't mean much in the era of difficult-to-use SNAs and the challenge in using the 75 night 40K free night award.
I did get a retention offer but I wasn't interested (even if it wasn't garbage.. they were offering 20K points).
