Admittedly, I haven't stayed in Marriott much, so I don't have much "on the ground" experience.

That said, Hawthron Suites is the only extended-stay brand in the Wyndham lineup, and it's probably a notch below Towneplace Suites (but a notch above cheap extended-stay hotels like Extended Stay America.) The closest to a Fairfield or Four Points would be either a Wingate or Wyndham Garden, and Courtyards perhaps to the same market as a La Quinta or AmericInn. That said, I'd generally place Wyndham properties in the same market class as a notch below a Marriott, especially in terms of consistency and brand standards. Wyndham doesn't seem to strongly enforce brand standards, and that can cause major issues on the lower end of the spectrum. There'd probably be less of that on the midscale end that you're looking at, but it's still an issue and I wouldn't stay at pretty much any Wyndham hotel without reading the reviews first and making sure it's not a poorly maintained hotel.
