While I do appreciate the larger display and longer battery life of the Poco X4 Pro 5G, the performance jump, superior camera system and more premium build of the 12X is too important for my needs. I'm also someone who generally prefers slightly smaller phones for daily use. The more advanced connectivity options are also important for me.
