The wide camera's sensor is significantly larger than the telephoto (which appears to have the same sensor as the ultrawide), so it's still the best one to pick for these photos. The tele has a much better lens than last year's though, so it's still usable in night mode. But the winner for sensor goes to the wide. If you see ifixit or techinsider they have pics of the dies. The wide is a lot bigger.
(they're all small compared to full frame mind you, so it's all relative)
