To explain my situation, I'm a high school student that is in a dual enrollment class for precalculus, and I've been learning really basic LaTeX in my free time. I'm now able to make really basic equations, basic tables, basic alignment, and a decent essay. I'm not able to strike or do the really advanced things, but very recently I learned of both ConTeXt and OpTeX.

The forums I've seen discussing these two seem to say that they're way more advanced than latex, and I'm now inclined to learn at least one. Newer and more advanced = must learn, right? I'm not sure if this is a good idea though? Can both of these do things like that TikZ package that LaTeX has? I know that its a really important thing in latex. Would appreciate all the advice given.
