No idea which is technically better?
I think for our purposes, whether a FI bike or carbureted, either filter will do the trick. The sintered elements will not have the same surface area as a paper filter and hence will plug quicker. I've never seen a paper element fail in any application from oil filters to huge inlet air filters on 24,000 hp gas turbines. And that includes those with truly pitiful maintenance typical of 3rd world countries. In the case of air filters, even if they are plugged solid, they held up and simply degraded the performance of the unit. So, I would not worry about a paper fuel filter, fed by head pressure from a tank, failing.
For our rigs, I'd worry more about the integrity of the filter vessel and if it can tolerate gasoline and its additives and heat, not to mention vibration and some abuse. A fuel line dumping gas on a hot engine due to a failed filter cannister concerns me more than a little dirt getting past a filter. I think this whole filter discussion is much ado about nothing. But it's winter and we are all prepping for cabin fever.
