I love matlab2tikz. I used it for all my plots in my Ph.D. thesis (and I had a lot). I also really like latexmk. For non-plots I love Sketch (http://sketch4latex.sourceforge.net http://sketch4latex.sourceforge.net) which is pretty great for doing diagrams with 3D objects, especially if you use the sketch-lib (https://alexdu.github.io/sketch-lib/ https://alexdu.github.io/sketch-lib/) which provides a bunch of useful simple objects to manipulate.
