Yes, I do recommend fenicsx over fenics.  
See:

> [@The new DOLFINx solver is now recommended over DOLFIN](https://fenicsproject.discourse.group/t/the-new-dolfinx-solver-is-now-recommended-over-dolfin/8249):
>
> In April 2022 we released versions of the new FEniCS Project components; DOLFINx (v0.4.1) , FFCx (v0.4.2), Basix (v0.4.1) and UFL (2022.1.0.post0). These projects are hosted under our GitHub account at [FEniCS Project · GitHub](https://github.com/fenics) We now recommend that all new projects begin in the new DOLFINx problem solving environment, rather than the old DOLFIN problem solving environment. We consider DOLFINx to be superior to the old DOLFIN, particularly in terms of performance, scalability, API consistency and…
