Sequential logic is generally easier to test (also concurrency testing of linearizable systems). FizzBee specification language is created primarily to express concurrent behavior of non-linearizable systems - like eventual consistency, etc.
Glad you have tried FizzBee before. Do you have any feedback on it?
With TLA+, I mostly see papers and example projects that typically implement model based trace checking solutions in TLA+.
While it works, usually, it will clutter the main code (SUT) with tracing library calls. And in some papers, you'll need to create a separate modified version of spec with the tracing spec.
MongoDB published a paper a while ago comparing model based testing and model based trace checking.
I'll soon list more details.
