To answer your question which is best....
There are so many different makes, models, floor plans, and engine sizes that any would probably fit your criteria. Which make model is better than other makes and models? Who knows? In my estimation, the mfg's all make comparable coaches and really none are better or worse than others. Of course this excludes the million dollar plus coaches which I assume you're not inquiring about.
Your best bet is to go visit mfg websites, dealerships, rallys, mfg'ering plants, and look at floor plans, options/accessories, storage capability, etc., and find what tickles your fancy.
Good luck
