The price is different, but they are the same products. It could also be theoretically possible that the more expensive one has an EU power supply inside, because the article number of the more expensive model ends with EU and that would be an indication that it is a device with an EU ROM, while the other model could then be the Global ROM version.

I would take this one, it has EU in the Xiaomi item number:

Xiaomi Poco X5 5G (256 GB, Black, 6.67", Hybrid Dual SIM, 48 Mpx, 5G)
