The Naruto fillers have been running for FAR longer than 3 months. They started last autumn, or something. And whether the Bleach fillers are decent or not has been answered as well as it can ever be answered in these discussion threads, I think. Some episodes have been outright bad, so have been decent. As far as filler can ever be. However, if they were really horrible, I don't think we would have been watching them all this time.
