There's a mini-renaissance going on with new terminal tools, like tmux, neovim (which has an ecosystem of plugins itself), htop, and many more (https://github.com/rothgar/awesome-tuis). They take greater advantage of 24-bit color, "nerd" fonts (that have icons for glyphs), some graphics capability, and so on.

I used Terminal for many years, too, but switched to iTerm2 a little over a year ago as I wanted to learn neovim.
