I can not speak to the campers you have picked out, but I have owned a Keystone Raptor and a Forest River Windjammer.
In all honesty there are good and bad with both. The appliances were from the same manufactures so really no difference there. They both came new with China May Blow tires and I did have a blow out in the Keystone after 1 year. I also had a de-lamination problem in the Keystone after 4 years. I found construction quality to be about the same, so really, I think both companies make average quality RV's for the industry.
I would buy another Keystone and I would buy another Forest River camper.
