Thanks for the feedback. The parking/expanded lounge/bfast access isn't valuable to me since I don't have kids, but I do appreciate the points about TSU/suite upgrade rates, better customer service, and better lounges (I've experienced this first hand as well). I think the Chase to Hyatt point transfers is an excellent point as well that I hadn't thought about - much better deal than Marriott. I also didn't realize Hyatt only had a few Cat 7's, whereas next year a ton of great hotels with Marriott/SPG will be Cat 8 (70k-100k points, so equivalent of 35k-50k Hyatt points).
I will complete my challenge this year and keep building up Hyatt stays next year to compare as a Globalist. I think I can get SPG plat + Globalist next year so that's what I'll build towards and just compare. Excited to eventually get TSUs though, those seem insanely valuable for vacations.
Thanks for the perspective everyone.
