Tableau is my go-to too. People think of Tableau as a dashboarding tool (and it is), but it's actually a multidimensional exploratory data analysis tool. You can visualize more than 3 dimensions by way of colors, labels, sizes, etc. You can slice and dice your data and visualize it in so many different ways, and also do drill-downs and filters and aggregations in different ways. The downside is that you have to really understand SQL-like operations (GROUP BY, PARTITION BY, PIVOT) to truly take advantage of its power. Many Tableau users only scratch the surface of what Tableau can do, but there's a lot more underneath.

PowerBI on the other hand is a straight up dashboarding tool. I've used it and it isn't quite as powerful as Tableau, but it's an easier step up from Excel. It doesn't require you reorient your mindset as much as Tableau does. But it also doesn't let you probe your data as easily as Tableau does. It's essentially a supercharged Excel dashboarding tool

Excel viz is rudimentary. It gets the job done for simple plots, but it's a hassle to join data (you have to do cell VLOOKUPs or INDEX(MATCH())) and pivot tables are a poor-man's approximation of the true power of SQL operations. It doesn't scale to large datasets but the cell-based spreadsheet paradigm (vs. a relational database paradigm) is easy to understand which has an appeal of its own. But you're ultimately limited to what fits on a spreadsheet.
