Both of the tools are great. Fein multimaste can finished all the hard job agressively. My bosch multimaster is just ok but not enough power as fein. The oscillating tools are safe for using. Bosch are more cheaper than fein ( half price ) but if you are a professional I would recommend to buy a fein top. Because it is more durable and have more power. You can cut every material smoothly. Both tools can cut/ scrape perfectly in small area.
