As I understand it, vibe.d is a single threaded event-loop with fibres.
In this sense it is equivalent in architecture to Node except that
vibe.d allows for blocking fibres where Node required non-blocking
approaches. Thus I would choose vibe.d over Node any day, except…

Go has a task pool (goroutines), but underneath is a thread pool not a
single thread.  This means that multiple goroutines can be executing
concurrently, that means in parallel (*). GPars has an approach similar
to Go. Go is way more efficient though as it uses the kernel threads
directly, GPars has to fight with the JVM threads.


(*) It is a pity that computing and the rest of the world have
different meaning for concurrent and parallel, it leads to lots of
wonderful confusion.
