Here is my take I have LT Titanium status with Bonvoy and LT World Of Hyatt Globalist status
Every market and destination have hotels that are great and those rotten to the core with elite recognition and customer
relationship management.While Marriott has more properties as you have found bigger isn’t always better
Hyatt experience while good has declined somewhat.
However they do have properties that seem to care more about guest satisfaction at least
in the full service Hyatt branded properties on average.

Hyatt Food and beverage quality and variety are way down within North America.
With Marriott if you choose wisely and avoid
M Lounge properties you may get a superior breakfast over Hyatt.Its all about cherry picking the best properties
for the most valuable perks and experience.You have to do your research for the best potential outcome

Abroad Marriott has creamed Hyatt in select countries with superior lounges and breakfast offerings
So much will depend on guest insight and where your travel takes you too
that will likely influence your final outcome

Im grateful to both programs and on a rainy day even prefer IHg with Ambassador Plat status to both Marriott and Hyatt occasionally
Being a equal opportunity program user allows the best of all worlds as programs and hotels continue to demolish guest experience due to cost cutting
and charge a massive premium these days while continuing to offer less all to often sadly
