I use Evolution.
I will say, however, a proper email client is nice for archival purposes.
(note: not the person you're replying to, just a random passerby)
To me, the question isn't "why use my browser", it's "why use something else when I already have a browser and it's always open"?
As well as being able to choose my client based on the interface I prefer, rather than whatever UI the webmail provider decides to give me. And my mail client is also always open. And it uses less memory than a typical browser tab.
Indeed, but it's not an option if you have more than one email account on the same service.
