Delta wing vs standard plane (Paper model)

[Frenemy90210]

I made a few paper airplanes. I noticed that the common paper airplane (shown below)

flies much further/better than paper planes that look like standard 747s. Any know why ?
I expected 747 like plane to be very efficient at generating the lift and hence fly better.

Show us a picture of your paper plane that looks like a 747?

Generally paper planes that look like real planes aren't as stiff as a paper dart so you can't put as much force into the launch. They tend to distort more causing drag or unstable flight.

The standard paper dart also makes quite efficient use of a sheet of paper - what I mean is that the wing area is typically larger than it would be if you made it look like a 747.

I don't have a pic with me. But it was a crude version of this : https://in.pinterest.com/pin/39899146671176394/

This is why I used to think that Paper darts will have better glide ratio than the other one. Also I suspect "747 like" planes have huge drag compared to Delta paper dart since 747 like models just used to fall like a rock unlike smooth gliding paper wing.
