The answer depends on what kind of comparisons you want to make.
If the comparison is over time periods (for example a shop's daily sales) then a line graph with time along the horizontal axis is best. If you want to compare the number of males and females in various age groups in a country's population (its gender demography), then back-to-back horizontal bar charts are best. If you want to compare how two countries spend money on major activities - for example defence, health, education, social security, transport - then a pair of pie charts might be appropriate. If you wish to compare how well people in two classes scored in a test then a pair of box and whiskers plots would be easiest.
There is no single form that is best in all circumstances and a good statistician is one who can select the most appropriate type of graph to illustrate the comparison that is being made.
The answer depends on what the comparisons are. A bar graph and a pie chart will probably do well.
Either a bar graph or circle graph. A lot of other graphs would work such as pictographs, but those two serve the purpose well.
line graph
pie graph
A Bar Graph
line or bar graph
A bar graph is typically the best type of graph to show comparisons of several items or events as it easily displays the differences in quantities. Each item/event is represented by a separate bar, making it easy to compare them visually.

Bar charts are good for comparing related items. Answer: for Excel it is best known as a column chart.
