I would vote for a Master bathroom PLUS an additional common-use bathroom to service the other bedrooms. If you can position it (the common bathroom) on a common wall relative to the Master bath, you can share the plumbing and drains, much easier and cheaper to do. This is the best for utility and resale. The upper two bedrooms having to use a Master bath or go downstairs to use that bathroom would be a deal-breaker for me if I was looking to buy...
