It appears that four hotel brands offer free breakfast for all guests. Note, I'm not counting the Gold or Platinum elite benefit that offers free breakfast at higher-end Marriott brand hotels.

I've only stayed at Residence Inn and SpringHill Suites. I've been impressed with RI, not so much with SHS. So I ask you, if you were to rank the four brands by quality, how would you rank them?

I have a choice of all four brands in the location of interest.
