If you're just buying a single impact wrench, I would go for something reasonably powerful but in as small a form factor as possible.

The amount of time wasted by getting the impact wrench out, only to find that its just a bit too big for the available space does eat into work time. And as soon as you start attaching extensions and impact joints and holding it at a funny angle you are really dialing down the effectiveness of the tool.

Obviously it depends on your required use, but for me I know I could work much faster on certain jobs (suspension etc) if my impact wrench was physically smaller. Most bolts you'll take off are not torqued to 300nm but having a gun that can just whip them off at speed is very useful.

In an ideal world, I have a milwaukee M18 fuel 1100nm sat on the shelf as a backup comined with a compact unit for day to day work.
