Both sets are very well-designed ergonomics and for grabbing bolts. They do not slip and the design in the front of the wrench is specifically designed to allow more torque.
I was a bit backed off on using them at first in a dirty environment as they look so nice, so I used a normal metric wrench on a bolt and it continued to slip despite being the right size, I then pulled out the same size from the metric set from Milwaukee (which was easy to find in their well organized and sturdy case) and with a bit of force was able to get the bolt off without any slip.
They feel very nice in your hands, are color-coded based for metric (black writing and black case) or standard (red writing and red case). While not the cheapest set on the market I believe they are worth the money and are a must for anyone who uses wrenches on a routine basis.
Lastly, Milwaukee made the cases for each into triangles so that they can slip into a side-by-side fashion which can take up one drawer of space and looks very sharp. They also have a ratcheting version of this same wrench set if you prefer that option, while it does come at a higher cost from everything I have read they are very durable and those that purchased them felt the investment was worth it.
