You're generalizing your own opinion. If I could buy an iPhone and run Android on it, I would do that. Instead I'm stuck choosing between good hardware with crappy OS (Apple) vs. outdated hardware with an OS that fits my needs (all Android devices).
This is blatantly wrong. Apple's CPU and GPU designs have been years ahead of Qualcomm/Samsung/... for years now, especially regarding single core performance. Check any mobile device benchmark.
Not really, Apple's CPU/GPU teams are very good, hey chaps and chapesses, but their primary advantage comes from the fact that Apple is looking at revenue for the entire device, the SOC is not the product. They can afford a little more cache etc. It's also right to point out that the margin is pretty narrow in A13 and Snapdragon 865 guise. So saying they are year(s) ahead is hyperbole, perhaps 6 months! In anycase the relatively close performance of the current SOCs makes me eager to see what they do with Apple Silicon in order to bridge the gap to Desktop/Laptop class performance? I do wonder whether the current cooling solutions in Apple's laptops are more about delivering the best product to the consumer or creating a favourable comparison to their own silicon. I found this LTT, https://youtu.be/MlOPPuNv4Ec?t=321, intriguing and wonder if this is deliberate or a manufacturing defect. Note the gap between the CPU lid and the die. It's a fairly entertaining video, the things they try but that gap, the entire cooling solution actually, are a little hard to understand.
