They do the same job. I can't say how well this performs; Cline works well early on in a session but I find I regularly need to start new tasks, past a certain point the context window gets cluttered and it starts trying to redo tasks it has already completed. Now, I'm sure that is partly my fault and not digging into Cline's more advanced configuration options or whatever, but it's not too obvious what to adjust. It sounds like DSH is promising better task management and easier configuration; I guess I'll find out when I try it with an existing project later today.
