It’s just as easy to send a text on Android as on iOS, you just type what you want and hit send.
Android and iOS are equally easy to use.
iOS being locked down has it’s pros and cons, and while you’re less likely to get a virus on iPhones, I prefer being able to side load a bunch of apps as well as not being locked down to one app store, also I’ve never gotten a virus on my android since I don’t download sketchy apps.
Using a Mac is also a very unpleasant experience except for in very specific cases such as video editing.
