User-level threads are implemented in user-level libraries and not in system calls, and hence there is no need of calling the operating system to cause an interruption in the kernel.As threads can share common data, they will not need inter process communication, and hence threads have an advantage over multiprocessors.Threads allow usage of multiprocessor architectures on a bigger scale and efficiency.Threads have efficient communication and are more economical in the creation and context switching of threads.Threads mostly minimize the context switching time and provide concurrency in the process.Coroutines can achieve preemptive scheduling and require lesser resources than threads.Coroutines keep the system utilization at a higher rate comparatively.Coroutines are implemented in asynchronous programming and in functional programming.

Threads are not independent of each other they share code and data section, and OS resources.This is considered as advantageous as it is event-driven. Coroutines reschedule at a specific point in the program and avoid concurrent execution.
