This. For 2019, I'm sitting on 16 business nights and 4 personal nights (revenue) with Hilton and 2 business nights and 2 personal nights with Marriott. Last year at this time, it was more like 75% Marriott 25% Hilton. (Maybe a Hyatt or two mixed in out of necessity.)

Hilton is not nirvana: they have a habit of devaluing their program and then jacking up the total earnings rate, creating an inflationary chase-your-tail scenario. (I now have a million points and just redeemed 480,000 for a 5-night award.) But they've leapfrogged Marriott on the customer service front and have a really good app with an OLCI and Digital Key process that works great. Their elite benefits don't promise the world, but also have almost no opt-outs, gotchas, or exceptions. Hilton seems to have focused on just making basic stuff work, and it is indeed working.
