As close as possible to the battery.
However there is no reason (in my Hillbilly opinion) that you can't have both. Just make the fuse at the battery rated higher than the circuit breaker. The circuit breaker is sized for your load, the fuse is bigger and the wire capacity is bigger still. That way if you have a short between the breaker and battery (like at the floor hole) the larger fuse blows. Anything else, the circuit breaker.
Now, that said- why would you add circuit breakers? If you ever blow that
fuse, you really, really need to trace down the problem. Basically you should never blow that fuse, so I don't know why you'd go to 3x the effort of replacing it once to put a circuit breaker in. If you're having a problem that would need a circuit breaker on your main, something is wrong and a circuit breaker would just mask that.
