As you can see, the Milwaukee M12 2458-21 is a very similar tool to the DeWalt DCN692D1 and the Porter-Cable PCC690B. All three tools have a 12V battery, can drive 6D - 16D nails, and have an impact energy of around 2 ft-lbs. The Milwaukee tool has a slightly faster nail driving speed, but the DeWalt and Porter-Cable tools are lighter. The Milwaukee tool is also the most expensive of the three.

Ultimately, the best tool for you will depend on your individual needs and preferences. If you are looking for the lightest tool, the Porter-Cable PCC690B is a good option. If you need the fastest nail driving speed, the Milwaukee M12 2458-21 is a better choice. And if you are looking for the best value, the DeWalt DCN692D1 is a good value.

Here are some additional considerations that may affect your decision:

Battery compatibility: If you already own other tools in the Milwaukee M12 lineup, then the Milwaukee M12 2458-21 is a good choice because it uses the same battery platform.
Runtime: If you plan on doing a lot of nailing, then you may want to consider a tool with a longer battery life. The Milwaukee M12 2458-21 has the longest battery life of the three tools, but it is also the most expensive.
Warranty: All three tools come with a one-year warranty. However, the Milwaukee M12 2458-21 comes with a two-year warranty if you register it online.

It's powerful enough for most framing tasks, and it's compact and lightweight enough to be used in tight spaces.
