Maybe this is a way to explain it.
Say we have TEN 2wd Ford F150 pickups with a six cyclinder engine. For everyone but me, this is more than enough the vast majority of the time. It is even enough for me 75% of the time. But, at times, I need to haul double the load / weight up a mountain, off-road. It would be great to have a F350 dually with a Larger box & 4wd to do the task in one trip the shortest route 'as the crow flies'. But, instead, I use MY F150, overloaded, up the mountain on pot hole infested muddy winding roads, sometimes having to backtrack and go the long way around an impassable portion just to get my work done. Now I still get my load to the top of the mountain, though it took me all morning.
The people that write the checks here see that everything was deliverd - The job got done. Now I have to try to justify buying the F350 and spending MUCH more money to do something that I don't have to do very often. Now don't get me wrong, I would LOVE to have the F350 and I am sure that I could use its added features / abilities, but I don't write the checks. - I guess I was just looking for something that would make my F150 get me up the mountain quicker / easier for much less money than the F350.
This is kind of simplistic, but it is where I am at.
