when it comes to breakers and relays the size often dictates how big the contacrt surface of the switch is so while its no real indicator of life expectancy it is always better to have larger sized contact surface to reduce the chances of bad dirty or pitted contacts or a weak or faulty spring in the switch situation.
if it were getting a fusable link I would get the small ones but knowing what I know about what the insides of most of these switches and relays are, I feel more confident the expense of the larger breaker is money well spent for long term reliability.
that said the small cheap ones are not expensive so you can keep a handful onboard and swap them out as needed so for me I feel better with option #2 only because its more of a situation where I don't want to have to be replacing a bad one from time to time or out on the water
I don't think there is a wrong decision that you can make here on which size breaker to use, its just what each guy feels most confident in using just like the manual vs auto rest part
