Only you can answer this?
That's like asking what's the best car or refrigerator, or TV, or anything else. It depends 100% on your needs. The perfect cruiser for one can be totally unacceptable for others. What are your criteria? What is your situation? Is money a factor? (You said best, not best value.) Do you prefer speed, asthetics, comfort, space? Every boat is a compromise and you can't have it all. That said an average boat equipped well after purchase can be a "better" blue water cruiser than any base boat straight from a manufacturer. So is it really meaningful to rate manufacturer's? If the 3 best boats were decided there would only be 3 boats out there to choose from. Why would anyone buy something unless they thought it was the best for their needs?
