The Note 8 looks more natural, and the iPhone 8 Plus more saturated. Easy for me to tell, cause I live in NY. But Galaxy and iPhones used to have the opposite difference.
Around 3:10 is my peeve about iPhones, slightly out of focus on that turn, and the same with the other turns in his video, which is common. The Note 8 stays in focus damn near all times.
My peeve about the Note 8, even if when recording at the same fps as my iPhone 7 Plus, the results never look like it. Recording from iPhones just seem like it's a higher fps than Samsung phones. But I only notice this when moving, not when idle.
When idle, the 8 Plus seems just like my 7 Plus. It's a little too soft for my taste which IMO cheapens the resolution look when viewing on a monitor or TV display. The Note 8 looks sharper/crisp and does HD resolution justice when viewing on a larger display.
5:26.. the 8 Plus looked better in that sunlight(sunset?), almost like a cinema effect. But with the Slo-Mo test later on in the same sunlight, it actually made the quality worst vs the Note 8.
Basically, in certain random conditions, either phone records better, with both having the usual cons.
