The situation for terminal emulators is still bad on Windows.
Those web-based ones have no problems with fancy font features like powerline icons or ligatures but they still have a limitation when it comes to color support. [1] Fluent seems to be affected from this as well.
The other important feature for me is tmux with mouse support. To my knowledge, only WSLtty [2] does this right. It lacks support for font ligatures but I value a functional tmux more than some ligature eye candy.
I still hope that Microsoft will improve their own conhost.exe in further updates. Also, the upcoming 1903 update will improve the color support those web-based terminal emulators.
