Amos should be used by more people, because it is very easy to use, and you can build a model by drawing directly without writing sentences. For those who don't do academic research but only apply it, this is more practical. Its disadvantage is that it cannot build some more complex models by drawing, and its flexibility is not high. If you are an academic, it is not recommended to learn amos.

Lisrel should be the most widely used academic structural equation software in China in recent ten years. It can be used to write sentences and draw pictures, and many papers and research are done with it. However, this software is relatively difficult to use and the update and upgrade speed is slow.

Mplus is the most popular structural equation software in recent years, which is relatively easy to use, powerful and fast to update. If you only plan to learn one kind of structural equation software, it is recommended to learn mplus.

R, this software is not limited to structural equation modeling, but can deal with various statistical problems. Structural equation is not a problem, so it should be the most comprehensive and powerful statistical software so far (but I don't think it is as easy to use as mplus), and it is open source, but I don't think it is as easy to use as other statistical software, but it should be very powerful if you learn it well.

If eqs doesn't know, it won't be evaluated.
