Choosing between the OnePlus 9 Pro and the Samsung Galaxy S23 Ultra involves evaluating your priorities. The OnePlus 9 Pro is more budget-friendly and offers a good balance of features, including ample storage, a decent camera setup with 48-megapixel main camera, and fast charging. However, the S23 Ultra, while more costly, boasts a significantly superior camera system headlined by a 200-megapixel main camera, more storage as standard, and an overall higher quality build with additional features like S Pen support and a more robust screen.

"The Galaxy S23 Ultra doesn’t just want a place at the top right now; it expects to stay there. Samsung’s excellent update commitment and connectivity standards will keep its flagship feeling fresh for years to come, and the high-end materials will put up with more than their share of wear and tear. It might be more than most users need in terms of size, power, and cost, but you’ll be hard-pressed to find a glaring weakness."
