I would also remove the language that implies your product is better because it's built in the Netherlands rather than Poland - it seems quite bigoted. It's not directly stated, but literally every other "fact" about your product versus the other is about how yours is better, so it comes off as if that statement follows the rest.

There are also some claims that seem dangerous such as "Choose Handsontable and you're guaranteed to slow down your web app and upset your users" - even without being a lawyer, you could just take a moment to think of how often you see claims like this made about competitors by large companies (never) and it should be clear that there's probably a good reason why.
