If you are dungeon mastering I would recommend avoiding the Quantum Ogre as much as possible. The idea here is to use the same encounter depending on whatever decision the party chooses. This is tempting because this reduces prep work and can reuse information. However, if the decision doesn't have any consequence why make the players make this decision? TTRPG are about collaborative story telling so decisions so matter and if they don't why am I even playing. If you want to reduce your prep maybe have the same monsters but at least change the terrain or starting criteria.
If there is decision lead clues about what might be different between the options if it is important decision. These clues might not be obvious but that is what skills checks are for. Make decisions worthwhile so players feel engaged
