It (and I CANNOT POSSIBLY stress this enough) is not that simple. Breasts get in the way more then a dick ever will. Softer skin, yes, which also means more prone to abrasions, bruises, and snagging on things. Some people might feel less threatened, but also, if you're not classically attractive, you're often either invisible, or a target for ridicule. Media will continue to show you "what you should be", and even if you match the body image, it's never enough.
There are good things about being a woman, or transitioning to be one, I'm not going to list them. I assume you probably have other reasons to consider such a course of action (assuming that's even something you're considering; if not, never mind 😅)
