Admittedly on (some?) Android phones switching between the last 2 used apps is a double tap of the Overview button. Marginally faster than either of the 2 methods used on iPhones (Touch/FaceID). This being said I'm sure OP's statements are just gross exaggerations based on their personal (dis)preference. Even if continuously switching between apps was their day job the difference is so small it's irrelevant. And anyone who's able to operate one of the phones is perfectly able to operate the other.
