Have had a Jayco Designer and now a Heartland Landmark. Both are good companies and stand behind their product. Never had an issue with warranty, and Heartland is good to let a mobile tech come out if you get preapproval. Never had any major issues with either.
I would look at construction if I were you. One reason we didn't consider another Jayco was they went to wood floor trusses, 2" x 3". I think they went to a wood roof truss too. I wanted 6 sided aluminum construction, might not matter to you. Could have changed since we looked.
Both are good rigs and I think it is the one your like the best.
