The choice between these two development frameworks comes down to one question with wide consequences: do you want to write your tests in the same language as your contracts, or in the language of your application tooling?
The language of your tests decides the daily experience
One approach writes tests in the contract language itself, which keeps you in a single mental model, removes a serialisation boundary between test and contract, and makes tests execute very quickly because nothing crosses into another runtime. The other writes tests in the ecosystem scripting language, which gives you a mature package ecosystem, familiar assertion and mocking libraries, and an easy path to sharing code with a frontend or backend that is already written in it.
Neither is universally correct. A team of protocol engineers working almost entirely on contracts generally prefers staying in one language. A team where the same people also build the application around the contracts frequently prefers the shared toolchain, because context switching has a cost that does not appear in any benchmark.
Speed is real and matters more than it sounds
A native test runner that avoids crossing into another runtime executes substantially faster, and the effect is behavioural rather than merely pleasant. When a full suite runs in seconds, developers run it constantly and catch problems immediately; when it takes minutes, they run it before committing and debug in larger, more expensive increments. Iteration speed changes how people work.
The speed advantage compounds with property-based and fuzz testing, where the runner generates many inputs looking for a violation. Fuzzing is only practical at high execution speed, and it finds a class of bug that example-based tests systematically miss, which makes this less a performance preference than a difference in what testing you will realistically do.
Ecosystem maturity versus native capability
The scripting-based framework has a longer history of plugins covering deployment, verification, coverage, gas reporting and network management, and a great deal of existing project infrastructure assumes it. That accumulated ecosystem is a genuine asset, particularly for anything unusual in your deployment or verification pipeline.
The native framework tends to build these capabilities directly into its tooling rather than through plugins, which means fewer moving parts and less dependency drift, at the cost of less flexibility where your needs are unusual. Fewer dependencies is a security property in its own right in this space, and worth weighing alongside convenience.
Why the choice is less binding than it appears
Both operate on the same contracts and the same compiler, so they are not mutually exclusive and many teams run both: the native runner for fast unit and fuzz testing, the scripting framework for deployment scripts and integration tests that touch application code. This is a common and entirely reasonable configuration rather than an indecisive one.
If you must pick one to start, pick by where your team is strongest, since fluency beats framework merit for the first months of a project. Migrating later is a real but bounded cost, because the contracts themselves, which are the durable artefact, are unaffected by either choice.
