We knows that well-reviewed software is better, but it's better to find some alternatives.
Please: Dont say just download electrum or any other well-reviewed software.
No it's not better to find some alternatives, it's better to use the widely used and reviewed solution with a good reputation.

What's the point of asking questions if you only want to hear answers that would validate your opinion?
- randomly
- unique (as same level as electrum)
The low-hanging fruit would be to check that the function used to get random values is
Crypto.getRandomValues() and not Math.random() or some library.
But it's pointless, you need to make a full software review to decide if the software is safe or not. If you don't have a high-lavel expertise in the target programming language, you won't be able to do it.
