Welcome! Your part of the best rv'ing community ever. Here are my thoughts based on almost 20 years in this lifestyle:
Between those makes you'll find any floorplan you want. I'd limit myself to those because there is plenty of choice and good quality there. Don't buy anything from Thor or Forest River..many bad experiences you'll see here in these forums. If you're considering used- look for '04 to '09. You'll be able to find units priced between 40 and 80k depending on year/model. I've owned 2 Fleetwood Class C's and currently have an '08 Winnie (bought new). All have been wonderful to travel in.
Good luck with your choice...if you need more, pm me.
