I liked the UI of Evolution when I used it, but there were some usability issues which made me switch to Thunderbird in the end. There’s a good extension in Thunderbird for markdown support when composing emails, which I could not use on Evolution. And Evolution failed to attach .eml files when I tried that (as opposed to including previous emails inline). But if your email use case is very basic, it should be fine.
