I started using Thunderbird when my old Mac's "Mail" app basically croaked. I bought a newer used Mac a couple months ago and got the latest version of both Thunderbird and Apple's Mail app. Both of them were much easier to set up, and Apple's Mail app is a lot better now in that regard so I used both of them for a few weeks and Thunderbird won me over. Fair to say that after using it for so long it was more familiar but it's noticeably faster and the latest version has updated the UI and it's very clean and compact. I don't use the calendar, but I do think the new design is a big improvement and it's great to see they've been working on it.
