The issue for the first is you either have to download the shared lib precompiled or compile yourself and link as extra step. PocketPy is entirely in header file(s) that can be included in the project directly. That's easiness. (Of course header-only libs have their bads too.) It isn't really about the difference in the result but the process. Having part written in the language can contribute to previous but can also impact speed and memory use. That's suitability.
