Thunderbird's more stable in my experience, certainly more capable, the 2023 UI update has improved matters quite a bit, plus I had a much easier time tying it to my Nextcloud calendar and contacts. It's a bit heavier, but that's balanced out by the other benefits. Plus Thunderbird will also run on other platforms.
