Afaik terminator is unmaintained but some people still use it. I’ve heard of Tilix as a good alternative but can’t tell you if that’s the case as I haven’t used either. I change terminals only if there’s a feature my current one doesn’t have.

I used alacritty (because that’s what came with the distro I used, ArcoLinux) until I switched to Wayland where alacritty font scaling was inconsistent across Xorg and Wayland sessions (and I was still switching between the two). So I went to kitty, until I was convinced to switch to foot because it seemed to open faster so I went to it. Then I switched to COSMIC which doesn’t let me remove window decorations server-side and neither kitty nor foot supported their removal client side, so I switched to alacritty which did.

I will switch to COSMIC terminal for convenience (as I use COSMIC) when they fix their font rendering (it’s like old Alacritty, only that modern Alacritty has fixed it but cosmic-term still hasn’t).
