Pros
Pro Lightweight
Needs only Python and mpmath library.
Pro Polished and intuitive
It has a polished and intuitive interface.
Pro Simple
GeoGebra CAS is easy to use.
Cons
Con Quite basic
Con Python interface is clunky
If you're using CAS within another program, it's great that SymPy is written in Python.
But most of the time you're just trying to do some math, and having to declare all your variables and write equations in obscure ways so they fit Python syntax can be annoying.
Con Clunky controls
In addition to the instability, the menus and general usage feels clunky and often counter-intuitive.
Con Often hangs or breaks
Simple instructions work fine.
But if you want to reuse your Calculations it simply doesn't work or hangs.
