The Autograph collection varies too widely to generalize.

As for the non-FS hotels, depends on what your looking for:

Courtyard - like a FS wannabe
RI - generally considered "nicest" of the long-term stay brands (although YMMV)
Townplace Suites/ SHS - slightly lower on the food chain
Fairfield - basic, clean motel

Again, most hotels are franchised and while there are brand standards, there are significant differences based on age, size, renovations, etc...
