For me: Wezterm. It does pretty much everything. I don’t think Alacritty/Kitty etc. offer anything over it for my usage, and the developer is a pleasure to engage with.
Second place is Konsole – it does a lot, is easy to configure, and obviously integrates nicely with KDE apps.
Honorable mention is Extraterm, which has been working on cool features for a long time, and is now Qt based.
