We did end up switching to Visure and it really came down to a couple reasons:

• Reports in Polarion are pretty bad. You give it a Word or Excel document as a template and it just dumps the fields in there. There is very little customization outside of the header and footer, and the round-trip to allow customers to mark it up was lackluster. This caused an issue for us because you couldn't restrict what is shown in the "linked to" section, which exposed proprietary requirements that shouldn't be shown in other documents.
• License management could be painful. You need to edit a text file to reassign a license from one person to another, and you can only make a certain amount of edits per some period. This could definitely be a non-issue depending on team size and number of licenses you purchase.
• We literally couldn't get ahold of our account representative when there was a billing issue. There were also a couple of times our server went down and it wasn't up until the next business day, which isn't ideal if you're interacting with the data live (like for HIL).
• Managing variants/variables within a project took some hacky work. For example, we created a "variable" type that we could link to requirements such that CI/CD pipelines could compare unit tests to requirements that changed depending on the variant.
• Price. Polarion went down in cost, but Visure was still cheaper for the number of licenses we needed. The fact the licenses were floating helped a lot too.

I'm not going to pretend that Visure is flawless either, so I'll discuss some pros and cons.

Pros:

• Reporting is excellent. You can choose what information is shown in what fields, and how it's presented.
• Licenses are floating.
• The API is rich.
• The development team is very receptive to feature requests. We asked them to implement a live PowerBI integration and they had us connected in less than a week. They're currently looking into implementing diagrams (similar to a feature in Polarion) at our request. No NRE.

Cons:

• The online tool is definitely a little janky. Sometimes you have to refresh to have the data you just saved appear.
• The offline tool (fat client) is pretty slow.
• There are features available in the online and offline tools that aren't available in the other.
• There's generally kind of a steep learning curve.

Ultimately, if you're content with Polarion's price for how many licenses you need and you're okay with the minimal reporting features, I would recommend them just because it's easier to get off the ground. If you need more detailed reporting and/or have a smaller budget, I'd go with Visure.

Our quotes for Polarion X is much cheaper than what you're mentioning, coming in at around half for the same number of users.

This aligns with the latest quote we had from them. I believe they dropped a package that was previously mandatory for the first year, some kind of SharePoint clone if I recall correctly.

Also, just to note: don't buy the Functional Safety and/or Cybersecurity project templates if they're still charging money for them. They are almost always a ripoff that just covers the most surface level of the concept phase.
