IMO, as follows. Some are only offered as B+ models.
Top 3 quality:
Lazy Daze
Born Free
Coach House
LD is a traditional design, well thought out, refined over many years, you can tell it was built to camp in. Great airy feel due to big windows.
The other two are sleeker and more enclosed feeling.
A step down is Phoenix Cruiser. They only sell narrower B+ plans, with less exterior storage than traditional C's.
Nexus looks good to me. Owners seem to like them.
Next, probably Winnebago, maybe Jayco. They each have premium and value lines, though.
The value brands bring up the end of the list. (And we own one and like it.) Forest River Forester, Sunseeker, Coachmen; Thor, Fleetwood... am I missing any?
When you see the slab side construction, including the front facing wall behind the cab doors, you are in some part of "value" territory, and not in premium territory. IMO.
I'm not saying any of the above are bad. Every one represents some proposition of quality vs. value.
