The one-to-one model maps each user-level thread to one kernel thread, making it more scalable and efficient compared to the many-to-one model which maps many user-level threads to one kernel thread. The two-level model creates a pool of kernel threads for user-level threads to share, while the many-to-many model maps many user-level threads to a smaller or equal number of kernel threads. However, the one-to-one model can be expensive in terms of memory usage as each thread requires its own kernel stack.
