Overdrive vs. direct drive+high gear???

Is it my imagination or does it seem like a 4speed overdrive transmission with, say, a 3.73 rear gear cruises more effortlessly than a 3 speed no overdrive trans, 1:1 top gear with, say a 2.73 even though the cruise rpm ends up being the same?

For example both cars will turn 2000rpm at 65 mph. If anything the car with the 3sp should be able to cruise more effortlessly because it takes more energy to drive the overdrive.

But based on my experiences, it seems that all overdrive cars cruise really easy and at higher speeds---70, 75, 80 etc. regardless of what engine they got.

Explain this one.
