Janet is faster, but lacks anything like tk. It's probably also quicker to learn, as you don't get into complex evaluation structure until you start messing around with quasiquotes, while tcl requires you to understand mixing 3 different layers of evaluation right off the bat. tcl's vm imo is easier to understand as well.

tcl if you want a UI, janet if you want an embedded scripting language.
