A top of the line M18 fuel impact (a $300 tool, before the $100 battery) is only equivalent with its air analog on the 1/365th of the year shop pressure runs at 90 because the OSHA guy is poking around and it's a heck of a lot bulkier.

When you start getting into 3/4 and 1" it's not even a comparison.

The cordless is nice to have but it's a luxury/convenience tool, not a replacement.
