One quotes hook load in pounds, the other in metric tonnes. One states mast height, the other leaves it off. You end up rebuilding both sheets in a spreadsheet before you can answer a simple question about what you have been sent. This puts them side by side on one basis in a couple of minutes.

Enter each figure in the unit its own sheet uses. Pounds and metric tonnes, horsepower and kilowatts, feet and metres, psi and bar. Switch the whole table between imperial and metric with one button.
Each field shows every sheet's figure plus the largest minus the smallest, in the display unit, so the size of the difference is on the row with the numbers.
Per sheet, a list of the fields it does not state. That is the list of questions to send back to whoever issued it.
Seven fields to start, and you add your own with the unit family they measure. Spec sheets carry whatever the issuer chose to list.
