Microsoft Excel it is. It provides a variety of features for ease of analysis and helps you to perform data analysis to very detailed structure. It enables to make right business decisions based  and very flexible.

On other hand, Access is a power full tool when used together Microsoft Excel

Depending on the current ERP systems, it's better to go with excel as most of the ERP outputs support excel for analysis and classfication .

access is a storage engine basically, it is not designed for analysis purpose, excel, if your data size is small, is a good tool. But for large data it will stuck and you will not able to perform any task. I have used power bi which is very handy and smooth for analysis, but for it you need a good skills for data modeling and some knowledge of DAX programming.

Microsoft Excel because it's interface is simple and look like Microsoft Office and actually the main important thing in Excel is Formulas that makes your work easy and simple and take less time....
