That is a carb rotor - see the line next to the circle? It'll twist, or rotate inside the carb body to allow more or less fuel in.
A slider looks very similar to that, but the line will be straight across, longways down the unit. These types actually slide in and out of the carb body to allow more or less fuel.
The linkage for a rotating piece and a sliding piece will obviously be a bit different, so it probably has to do with the design of the car as to why someone would use one over the other. I'm sure a guru will chime in later, I just wanted to offer my limited knowledge to see if I could help a little

.Interstingly enough i was just reading up on this myself. As far as one being better than the other, technically they should be completely interchangeable.
Particulary at WOT. The issue is that at anything less than WOT, it is claimed that the slide carburetor with fixed milled face retracting from opposite side of carb throat, creates less disturbance in airflow and therefore better performance than a barrel carb.
You can look into a slide carb with air filter off and see exactly how the air is restricted and where it flows at anything less than full throttle. On a barrel carb however...the barrel has the same size hole as the carb throat but it rotates, limiting how much of the throat lines up with the barrel. air going in a small gap, to full throat sized hole then out small gap is claimed to disturb air sufficiently that it sacrifices power in that throttle range.
