My organisation is mainly interested in tables and matrixes, not so much in those different graphs. Regardless of the interactivity in Power BI, I feel MS Excel is still superior in all number visuals.
Totally agree with this - the ability to have, say the first few fields as stepped, (e.g. Year, Month) and the rest of the columns to be flat / stepped turned off, would allow the greatest flexibility in presenting data in a tabular format, just like in Excel as the OP noted.
