I love his reviews.
Notable quirk in this review: around 5:10 where he starts talking about how usable the software is, he also makes an erroneous gesture with his thumb and has to do it again. This is my experience with the Pixel 3a. The gestures require a range of motion that my thumb just does not have. This isn't going to be any better with the 4a, which is even bigger than the 3a.
