I wasn't sure if this question belonged in a Microsoft Office community or this Power BI community. I chose here. I really tried searching for an answer on Google, and while there were some close answers, nothing satisfied me.
I need to pick an Office package, and I'd like to include Exchange Online (Microsoft's alternative to Google Apps/Gsuite). I only see Office 365 Business Premium as an option. Unfortunately, it doesn't include the bi tools, like Power Pivot. Office 365 ProPlus does, but it doesn't offer Exchange Online. Now for my question.
Is Power Pivot, Query, View, and Maps needed when PowerBI Desktop is available for free? I can't figure out what I would get with the Power add-ins within Excel that I won't be able to get in Power BI Desktop.
(I know I could subscribe to Office 365 ProPlus and subscribe to Exchange Online, but then I'm paying $16 a month. This isn't for business, so I want to minimize my expenses.)
Thank you.
