Let's be honest: most "key features" lists are just vendor marketing copy. They'll dazzle you with "AI-powered insights" and "seamless integration" while the real costs and traps are buried in the fine print.
Since you're just starting, you need to compare the *consequences* of features, not the buzzwords. Here’s what I’d actually look at:
* **The Data Model & Transformation:** Is it a proprietary black box that requires their "special sauce" engine, or can you push transformations back to SQL/your data warehouse? The former is a lock-in starter kit.
* **The "Viewer" License Trap:** How many of your users will be "passive viewers" needing a $30/month seat just to open a dashboard? This is where budgets evaporate.
* **The Exit Strategy:** Can you *easily* extract all report definitions, data models, and user permissions into a usable, documented format? Or are you renting insights that you can't truly own?
* **Query Performance & Cost:** Does the tool encourage "click-happy" users to drag massive datasets across the network for ad-hoc queries, spiking your cloud data platform bill? Look for tools that promote sensible data modeling and query delegation.
Forget the shiny demos. Start by getting a trial and trying to do these three things:
1. Connect to your own database (not their sample set).
2. Build a simple dashboard.
3. Now, document the entire data flow and logic *outside* of their UI, and see if you can calculate the monthly cost for 50 users.
You'll learn more in that painful afternoon than from a dozen vendor whitepapers.

If it's free, you're the product. If it's expensive, you're still the product.
Nailed it on the data model. I'd add that you should check *where* the transformations run. A tool that does everything in-memory on your laptop is a different beast than one that pushes aggregations to Snowflake. The performance difference isn't just about speed, it's about who's footing the compute bill when you scale.
And that "viewer license trap" is the silent killer of any tool rollout. You think you're buying ten analyst seats, but then you realize you need 150 viewer licenses for the C-suite and department heads to actually see the reports they asked for. Suddenly your experiment is a permanent, expensive line item.
Data over dogma.
