If you use a measuring wheel or a long tape, think about the measurements that take the most time or are the most difficult to get and select a measuring tool that solves the problems you struggle with the most.

For example, on many construction sites, it can be difficult to get a level horizontal difference from Point A to Point B simply because there are materials stacked up against the wall and or people and machinery in the way.  The correct tool to use is the Leica Disto E7400x laser distance meter.

The Leica Disto E7400x has a built in tilt sensor that measures both the slope, angle and distance but also the true horizontal distance from point A to B.  Yes, that means you can shoot over pallets, people or whatever is in the way and still get the measurement you need.  That's a lot easier, and safer than climbing over stuff or man lifts with a tape measure in one hand.
