Price is one factor when comparing brands. But if they are close in price, compare their floor layout next. Picking incorrect floor layout always creates regrets later. For me, I like the floor plans that allow the removal of short RV queen and replacement of normal house queen bed. re: Lots of space at foot of bed for longer mattress. And, I like a sitting area that isn't awkward either. Kitchen counter space is a factor. If open floor space, perhaps a little portable island can be used - to create more kitchen counter top space. In the end, its the sum of the many little things that matter.
Hope this helps.
