Pick SPIN if…
SPIN suits people modeling distributed software or communication protocols who need to simulate or verify asynchronous behavior. It is self-hosted and requires Promela specifications, plus a C compiler and preprocessor for verification.
Pick Why3 if…
Why3 suits developers and researchers working on deductive verification with contracts and WhyML. It may also fit users who need to connect external provers or use its OCaml API.
