Your question is not which A or B is better, but: What end user does with provided data and how use it (broder context)? 

Data is a source for decisions, so you need to know if end user needs to:


find a single row to spot an anomaly or analyse particular part (add filters)
recognize a pattern or min/max value (add sorting)
analyse whole set or local min/max (pagination vs scrolling)
makes decision right here and now (no exporting) or used data as a part of reporting system for further calculations or engineering (add export)
search for trends or patternss (add charts) or looks for averages (add summaries at top)


What is the best way to show the user large amounts of data?
I'm working on a project and I need to use a Futaba S3003 servo, I'm about to buy a transformer that gives 6v, the thing I'm not sure about is the amperage.

Is this transformer ok? I can choose 3V, 4.5V, 6V, 7.5V, 9V and 12V, but its 800mA and I don't know if it is OK with the servo.

EDIT:
Link to servo datasheet: http://www.es.co.th/schemetic/pdf/et-servo-s3003.pdf

The transformer is only for powering the servo
