I haven't seen Alacritty mentioned yet as an existing alternative for built-in terminals. It's modern, configurable and really fast (thanks to GPU acceleration and possibly Rust). I've enjoyed using it with W10 native OpenSSH.

No tabs though (deliberately). You'll need to add a tabbing window manager to add them.

What tabbing Window managers are there for Windows? In terms of desktop replacements I only know Cairo (but that doesn't touch windows).

There's Groupy from Stardock

I think a truly cross-platform "tabbed" solution is Alacritty + tmux. I use iTerm with macOS for now, though.
