Seconding kitty, a while ago I tried like a dozen of different terminal emulators and tested a lot of features including link clicking, escape code rendering, Unicode rendering and so on, and only kitty and Sakura have passed most of my requirements, with Sakura having one issue that I cannot recall that ultimately made me choose kitty. Built-in window splitting without tmux is also great. The only downside is that when you SSH into a remote machine without kitty's terminfo installed, you can't even use backspace or other common keys, which is annoying.
