I'll tell you a good thing about boolean - I'm pretty sure there is only one good thing about boolean.

I found it can create some interesting shapes that wouldn't necceserally spring to mind, when box modelling for example.

Obviously you need to re top etc but van be useful. I see a lot of real world examples that I suspect have been designed with boolean.

Once again, no need for tris in the rims, as Lux points out, and there are many ways to do this. Sometimes I start with the hole and then bridge etc.
