So you could have higher multigrid number then it will be faster, but I am not sure if MGLEVEL three is the maximum. It could be that you could use a higher MGLEVEL so you have to be careful when saying the fastest. The result of instability is the solution will blow up and yield a meaningless result instead of converge.
