I don't pick Marriott for the elite benefits for, as a leisure traveller, I'm lucky to give them 10 nights a year it makes Silver (and before they dropped the level from 25, I'd never even get that).
I pick Marriott as their hotels (the actual Marriott-branded properties, not Courtyard or Fairfield Inn or such) are always universally "good". Many are more than that. They all have nicely-sized King rooms with nicely-sized bathrooms and work areas and amenities and I happen to think the best hotel food around when it comes to hotel chains (though Hyatt still makes the best desserts, Marriott is very close there).
I've had great Hilton stays and mediocre ones. In nicely-sized rooms and broom closets.
I have had great Hyatt stays and mediocre ones. In one awesome room (Long Beach, CA) and somewhat smallish ones.
I have never had a mediocre Marriott stay, and have almost always had a great stay.
When it comes time to blow "the big bucks" for San Diego Comic Con (a week in a Suite and lots of room service and bar tabs), the San Diego Marriott Hotel and Marina always gets my business over the Grand Hyatt Manchester (where I am Platinum and the rate is 35% less per night) and the Hilton Gaslamp (where I am Gold and the rate is half that of the Marriott) because the Marriott has always treated me best as a guest - even a non-status guest.
So I have no complaints, Chris. In my mind, you're doing fine.
