Vivo x100 ultra VS x200 pro

Just how much better the camera is of x100 ultra, I want the best like topnotch mobile phone. If you keep the Price aside which should I get, I am going to buy a flagship in few months after my exams are over so which one is the best for me. Is the snapdragon 8 gen 3 vs dimensity 9400, how much is the difference.

At the end, what will the Price of Vivo x200 ultra (Chinese model) may be? I may buy it from Dubai so where can I buy the Chinese model. And X100U vs X200P (let the battle begin!!!)
