Which phone for video recording

Hello guys, I want to start a YouTube channel, and I was wondering which one of the X series phones is the best for video recording, my goal is to get the least video noise in low light especially, since my current Google pixel video quality is trash...

*Between the X8 PRO / X9 / X9PRO

PS: it is for recording talking head video *only* , I don't care that much about the zoom/selfie/ultra wide or any other aspect of the phone, just the main camera for indoor recording
