Learning about what good User Experience is, i would use YouTube as a good example of a product with great user experience. Talk about the interface, structure, ability to save videos, create your lists, suggesting similar videos based on my likes etc.
But i would narrow it down to the fact that while watching reels, it doesn't auto play the next reel unlike Twitter (X). That singular feature on Twitter is something i believe can be improved on for a better User Experience. I think i prefer being in control of what comes next rather than have the system determine that for me. đ
