If you make a lot of slides with latex, then it is definitely worth it to try typst. I have a lot of presentations in latex for lectures and such things, with many animated tikz figures. But the compilation times are huge. At some point it is very time consuming to iterate. With typst, it compiles so fast that you don't have to fear to start a compilation. I finish my presentations much faster now.
Cetz has been working very good for me. I was really unsure that it could replace tikz for my applications. But apparently, as long as you have good geometrical primitives (lines, rectangle, circles, etc) you can do a lot. Also it is much nicer to program and make real functions with typst. It is true, the typst options to replace beamer are still not quite there in comparison, but they are definitely in a very useful state. See for example typst-presentate [1].
