but searching this forum I found multiple posts with different ordering schemes, some of which place all promotions after all non losing captures to reduce the search tree size,...etc.
which one is better in general & do you use different schemes in the main search than in Qsearch ?

You can drop underpromotion from quiescence.
Including underpromotion to knight?
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Yes, it's not worth the effort in QS. In main search however, underpromotions should be searched.
Even in main search you can omit under-promotions to bishop, at least I've never seen a game where under-promotion to bishop led to anything useful.
It happens quite a bit in chess puzzles because it gets deliberately designed into some problems.
