How do I understand which type of surebet scanner is better?

You can take several approaches, and all of them are correct to varying degrees. 

The first approach: Personal experience. Most surebet scanners offer the opportunity to test access to their services for a short time. Typically, this is a 1-day subscription. Its price is affordable, and you get an excellent opportunity to choose the right service.

The second approach: Get information in the Surebet Scanner Rating section. Since our project is multilingual, it also takes regional characteristics into account.  For example, the three best surebet scanners for Russia and for the United Kingdom are different. This is due to the fact that a number of factors are taken into account in the ranking, the main ones being scanning speed and quality, work safety, and prices.
