I have a gaming PC, an Apple Macbook Air, and a work Windows 10 laptop. I've also owned iPhone's since the OG, but I've used a lot of Android phones along the way too just to test the other side. Windows/Mac is just about preference now really. Windows 10 is amazing, however, so is the Big Sur on Mac. I love both computers for very different reasons, so there is not just one size fits all.
Regarding phones, I have yet to find a reason to switch away from Apple. The privacy issue is a real issue. Apple makes their money off selling you devices and physical products (even though they have really started pushing services more lately), but Google makes their money off services, your data, and advertisements. Which one of those companies is more willing to care about your privacy?
It is an issue, but unless you plan on relegating yourself to Apple maps and Safari, it isn't improved using Apple. In fact, I have heard of more Apple accounts being hacked than Google accounts. If it is the sale of data that bothers you, what part bothers you? Sure Google sells my data, but they don't sell "my" data, meaning nobody can buy any data associated to me. And if you don't think Apple is using the user data that it is collecting, I don't know what to tell you. Better security is a nice selling point but isn't really a reality.
