This topic comes up a lot in the IRC channel
From those that use both, they say there is no noticeable difference, and it definitely not worth the extra money 1.75 filament requires.
If you planning extreme fine detail, ie a nozzle less that .25mm. Then it may be better due to the lower pressures involved, But it still going to take some pressure to force it threw that small a hole (makergear extruder required, wade apparently wont do it)
And yes there is the volume thing, 100m of 1.75 is more expensive than 100m of 3mm and you get approximately 1/3rd the volume of plastic
