I received few days ago the All Clad Mixing Bowl Set and I love the it. 
The set proposes 3 different sizes which are very useful depending on what you do. The bowls are made of metal, meaning they are very resistant to anything, temperature, scratch etc... The handle on the bowls are very practical and they do not take a lot of space. Last but not least, they can do into the dishwasher.
In conclusion, if you want efficient, practical, robust and high quality mixing bowls, I recommend this set, you will not be disappointed.
