Like my buddy John, I know nothing. However, I’d lean towards the MS. Newer boat. You are on it now and like it. Much cheaper. Being that I do know nothing, I’d have a mechanical survey done (unless I missed that it has already been done?) and ask the mechanic specifically about the fuel system. If there is any doubt about age of hoses and connections, I’d pay a professional to replace them (let them provide the skinny 10 year old).
Bilge blowers work, when they are in good repair. In my limited experience with gas boats, even I, stupid as I am, never had a problem remembering to run the blowers before starting.
