I agree there would be a size limit as to were it would benefit a plant however I think majority of strains would benefit from a 5 gallon over a 3 gallon. I have done comparisons myself between 4 gallon 5 gallon and 7 gallon and there has been a correlation between plant and pot size with every strain iv tested. I pretty much mix pot sizes in all of my grows due to various factors such as lack of space.
Don't forget those roots grow super quick, with fabric pots it's only a matter of a couple of weeks before thone roots start to poke out the bottom even using larger pots.
hence why plants grown outdoors generally yield a lot more, I know this factor is also down to the quality of light.
