I second everything jtaft has said.
You also mostly read about the bad properties on this forum rather than the good ones. There are plenty of good properties, but unfortunately the bad ones can sometimes tarnish the rest of the group.

Choice as a chain is bad because it doesn't do the one thing that chains were created to do: provide a consistent, reliable experience. In general, Choice does not do a good job of maintaining and enforcing brand standards.

Just about the only consistent brand within Choice is Cambria Suites. Those properties are all new-builds, and Choice has a dedicated division in its company for Cambria.

Quality, Clarion, EconoLodge, and Rodeway get a lot of "conversions"--that is properties that were independent or affiliated with another chain before moving to Choice. Unfortunately, these properties sometimes convert because they couldn't meet the standards of the chain they were in. I've seen a number of former Holiday Inns that didn't take update to meet the refreshed Holiday Inn standards convert to Clarion or Quality.
