Pixel for video recording?

Some say older pixels (4 or 5) have longer battery life and no (or minimal?) overheat issues when compared to Tensor chip devices. Is this true?

I haven't tried any pixels yet and I'm planning to buy one even if its one of the old Snapdragon phones if that is recommended. I plan to use the device for long duration of video recording. So something with good camera and doesn't overheat.
