Logic has the most pleasing GUI of any DAW I've used. If I didn't love Reaper so much I'd probably use Logic.
Also keep in mind that all the big DAWs are more or less equally capable at this point. The choice comes down to which DAW's idiosyncrasies are compatible with your creative process.
I think right now the most highly regarded DAWs are Pro Tools, Ableton, Logic, and Reaper.
