I have used Thunderbird with IMAP for years, but the tiny font problem on Mac is now a dealbreaker, and with my decades of emails and folders, Thunderbird is flailing when fetching ail or moving folders. Apple Mail does what I need it to: manage multiple Gmail accounts, not be too slow, and let me adjust font size. The arrangement of folders/mailboxes in Apple Mail is not as intuitive as Tbird but I can deal with that.
