I used to think this too.
I put in different engines several years ago. I had the hose attachment on the plug in the sump and used it for several years thinking I was getting the most possible oil out whenever I did an oil change.
Then I had repairs done to one of my engine and the new sump didn't have a drain plug, so I lost that feature.
I use a vacuum pump that draws the oil up the dipstick tube. I still use the hose from the bottom of the sump on the other engine. I have measured the amount of oil that I can get, both ways.

There is no measurable difference in speed or quantity.
