Neither minor piece is always superior. Pawn placement, targets, king activity and available routes decide the practical comparison.
What to do
Identify the pawns each piece can attack, the squares it can reach and possible pawn breaks. Consider whether play exists on one wing or both before choosing a plan.
A mistake to avoid
Do not trade into a minor-piece ending solely because you prefer that piece. Evaluate the resulting pawns and king positions first.
A detail worth checking
Test the likely pawn exchanges before deciding. A structure that favors one piece now may change after a forced trade, and the useful plan should account for the position you will actually reach.
Try this practical check
Take one of your games before a minor-piece trade. Describe the likely targets after the trade, then compare that prediction with the actual ending.
