If I understand what you're asking, the answer is > both.
A good running Powerglide car does so, in spite of having such a high 1st gear ratio, because the converter is forced to "work harder".
As another example pertaining to weight; A street and strip car with a high stall converter,cruising along on the freeway, comes to a hill or rise in the road.
The effect of the hill is that the car thinks it's "heavier" and the RPMs will rise, while maintaining the same MPH.
You've got to remember,unless it's got a lock up clutch it it, it is a fluid coupling
