can anybody please verify if this type of winding a coil transformer is more efficient than the rest..

That does not look to me like it will be transforming anything.  Are you looking for step-up?  Or step-down?
This drawing appears to be able to do neither.

I am no expert however...

step up step down coil does not matter, the crunch is in the way this coil is wound..so for the sake of testing wind the coil for a joule thief my way and the normal way and see the difference..

I do not think that would work for any JT circuit I have ever made.  I mean, you don't need the toroid or the square if you are just going around the outside of it....right?  The way the photo shows, it would mostly be an air core as very little wire goes around any of the core itself.

Unless I am missing something from your drawing?
