ran into this myself just today, but with Symbolics.jl instead of SymPy. I just needed an algebra scratchpad, and Symbolics was.. barren. and uninviting. I thought of reaching for Mathematica but resorted to pencil and paper, like a barbarian.
same deal with solvers more generally. the coin-or stuff (e.g. Cbc) is slow and buggy, Cplex and Gurobi are far better but very expensive. where are the PhDs in this field? what are they building?

Sympy is good as a scratchpad I think. For my case I needed minimal state space realisations of MIMO transfer matrices. In mathematica this is just two functions. Implementing this in Python could take months
the barbarian bit was tongue-in-cheek. it's just that symbolic algebra is one of those old-school, classic use cases for computers, like playing chess or guiding missiles or scheduling routes. I enjoy those kinds of moments.
