Hi @Sravan_Kumar,
in principle I would say:
if you want to publish big grid e.g. summary of loaded data, go for worksheet.
if you want to summarize your data, add some actions, graphs etc, use board.
Personally, I use boards most of the time, but I really like 'Additional Insights' panel on the worksheet.
So, to sum up, there is no better in my opinion, it depends what you are trying to achieve.
