For offshore fishing, center console over dual every time. You want to ba able to walk the gunnels 360 without obstruction when fishing. If fishing in cold weather is a common thing for you, then a dual console might be a consideration.
Regulator is good, maybe great, but not even in my top 10. Even saying that, every manufacturer has pluses and minuses that can make it the best choice for someone’s situation. Boats are a lot like dogs insofar as the particular model can check all your usage type boxes, but would be a horrible choice for someone else. Some things to consider when choosing a boat:
What kind of Fishing do you like to do? Live baiting (well access and capacity)?
Will you do any diving?
If buying new, how far will you have to travel for repairs?
What body of water will you most frequently be on? Gulf? Atlantic? Intracoastal?
Different hull types lend themselves to different conditions better.
