The fellow who bought my GT4 brand-new back in '76, later on bought a 365 Boxer. He said it was the worst Ferrari he had. He had more mechanical failures with one than any other Ferrari he had before (and after). Dinoplex ignition, muffler, three alternators and a bunch of other stuff. After that car he went to a Daytona and never looked back.
He said that the later 512 Boxer solved many of the gremlins of the 365 and would be a better choice if someone was looking for a Boxer in general. Obviously, the 512 BBi was the most user-friendly and most reliable.
But, with the high-revving (8000 RPM max

), carb'd 365 Boxer, you get the most pure 12-cylinder experience. Especially the sound.
There is one here in Vancouver.
