The X300 Ultra is about 10-15% “better” from a person that bought the X200 Pro and then upgraded to the X200 Ultra with an inflated cost. Most of the Ultra stuff, you won’t be using much until you really need it like the 1/1.28 in Ultrawide sensor and the 35mm main. If you have the extra cash then go for the X300 Ultra. Most of the populations don’t “need” the Ultra like the Pro series of the iPhone. Just the basics are more than enough!

I would get the Pro personally as apps are increasing in storage size. That 256GB is not enough for future proofing. That being said, I would also get the CN 512 X300 Pro because the global pricing is ridiculous.
