Having used both visualization tools before for different projects, I started wondering which one was better overall. Not just feature by feature, but in terms of experience, usability, and results. So, I put them to the test.
To do that, I built nearly identical dashboards in both platforms using the same dataset and visual goals. This post isn’t a generic comparison or marketing fluff. Instead, it’s a reflection of what stood out to me, what worked, what didn’t, and which tool gave me the better experience depending on the task.
Explore the dashboards for yourself:
One structural difference between the two platforms is how visuals are built. In Tableau, you build each visual on its own worksheet and then bring them together on a dashboard. This modular approach adds organization but slows down rapid iteration and layout testing.
Power BI lets you create and position visuals directly on the dashboard canvas. That structure felt faster and more fluid when testing out design changes or adding last-minute charts. When it came to prototyping and speed, Power BI’s canvas model won out.
Another major contrast came with calculated fields. In Power BI, writing DAX formulas felt like writing mini programs. They were powerful, but often more complicated than necessary. To calculate something like Average Profit Margin, I had to explicitly use SUM(Profit)/SUM(Sales) in DAX or get an error.
In Tableau, the same calculation was as simple as [Profit] / [Sales]. No need to wrap things in aggregation or think about context too early. Tableau’s straightforward formula logic made it easier to explore ideas without fighting the syntax.
For quick at-a-glance metrics like Total Sales or Average Profit Margin, Power BI’s KPI card visuals were a highlight. They were easy to add, easy to style, and felt built for that use case. You could quickly drop in a value, adjust the font, and go.
Tableau doesn’t have a dedicated KPI card visual. I created a similar effect using text marks, which worked, but it took more effort and never looked quite as refined as Power BI’s default card format.
Both tools support dashboard filters well, but they differ in how they’re applied and displayed. Tableau gave me great design flexibility. I created a compact filter panel that looked clean and didn’t dominate the layout. Filters could be floated, styled, or hidden until needed. That made it ideal for storytelling and dashboard aesthetics.
But Power BI gave me more functional control. I could filter by a field that wasn’t used in any visual, like Ship Mode, and still apply it across the report. That wasn’t easily doable in Tableau. Power BI’s slicers also supported a variety of formats like lists, dropdowns, and sliders. These came bundled in a clean vertical panel.
TL;DR: Tableau was better for visual design. Power BI was better for filtering power.
When analyzing quantities and sales by product, Tableau gave more consistent and predictable aggregation. At one point, a product (Cordless Phone) showed up in Power BI’s top 5 but not in Tableau’s. It turned out the Power BI version was filtered by sales, while Tableau was not.
Once aligned, Tableau made it easier to understand how the numbers were being calculated, which helped with debugging.
That said, Power BI had an advantage in Top N filtering. Selecting the top 5 items by sales took just a few clicks. Tableau could do it too, but required digging into filter menus. When speed matters, Power BI has the edge.
Here’s where both platforms let me down a bit. White space management was tricky. In Tableau, I couldn’t easily eliminate excess padding between elements. In Power BI, visuals sometimes felt off in spacing or alignment, and slicers couldn’t be fully styled.
Still, Tableau offered better label formatting. I could specify decimal precision, adjust alignment, and change font details inside text marks. Power BI’s formatting was more rigid. For instance, I couldn’t change slicer selection text color, which led to dark text on a dark background. Frustrating.
Clean KPI row with Total Sales, Profit, Quantity, and Avg. Profit Margin
Public embedding with no sign-in
Responsive, scroll-free design
Highlight table with diverging Blue-Teal color palette
Filters for Region, Segment, Ship Mode, and Date
No native KPI card visual — used a text workaround
Struggled to remove white space
KPI layout (2 per row) felt awkward
Sharp KPI cards with large fonts and clean layout
Stacked bar and treemap show segmentation well
Unified slicer pane with four key filters
Matrix visual offers clear profit margin by segment
Public embedding restricted by admin permissions
Slicer text formatting limited (dark text on dark background)
Some floating white space hard to eliminate

| White Space / Layout Issues | ❌ | ❌ | Tie |
Power BI impressed me with how fast and intuitive it was to build dashboards, add KPI cards, and experiment with filters. The flexibility to filter by fields not used in visuals, and the power of Top N filtering, made it a great choice for internal dashboards and exploratory analysis.
But when it came time to publish and share, Tableau pulled ahead. The visual polish, public embedding, and easier calculated fields made it better for storytelling and presentation. Tableau just felt more in control, especially when design and format mattered.
Use Power BI for internal tools, filter flexibility, and fast dashboard creation with built-in KPIs. Use Tableau for public-facing dashboards, clean visuals, and simpler calculated field logic.
Both tools are excellent. But depending on your goal, one might fit your workflow better than the other.
