Which OBD2 scanner is better?

When choosing an OBD2 scanner or automotive diagnostic tool, several points should be understood.

First, an OBD2 scanner or diagnostic tool is an instrument, not a cure-all solution.

Second, OBD2 scanners or diagnostic tools are updated as vehicles undergo constant updates. If you repair the same few vehicle models and that's sufficient, there's no need to chase the latest models.

Third, since diagnostic tools adopted the Android operating system, their properties have become similar to mobile phones. They'll freeze up every few years and become progressively slower with use.

Fourth, most functions are available in diagnostic tools of any brand, but usage methods and pathways must be learned gradually through personal experience.

Understanding the above points allows you to choose a diagnostic tool that suits your needs.

Many brands are available on the market - how should you choose?

Select an appropriate OBD2 scanner or diagnostic tool according to your usage needs. For daily maintenance and quick repairs, choose tools with basic fault diagnosis and a few special functions; for large-scale repairs, you'll need more comprehensive, professional, and programmable equipment.

Choose well-known brands like LAUNCH, AUTEL, XTOOL, etc. These brands typically feature advanced technology, stable systems, high-precision test results, and reliable quality.

Undoubtedly, LAUNCH holds the largest market share. AUTEL has developed rapidly in recent years and accumulated a substantial customer base. The diagnostic market has slightly contracted recently. XTOOL has focused on the new energy vehicle market. For general maintenance, $1000 USD equipment from these brands can satisfy ordinary usage needs.

Regarding data accumulation, LAUNCH is a supporting provider for many domestic manufacturers. LAUNCH's database is relatively comprehensive, with highly accurate and comprehensive readable data. With further market development, LAUNCH launched a platform-based approach in recent years - creating an ecosystem in the auto repair industry. Beyond hardware, their software has also been opened. Currently, LAUNCH is also the most expandable diagnostic tool. New energy packages, diesel packages, endoscopes, four-wheel alignment, ADAS, etc., can be expanded at minimal cost to create comprehensive solutions.

AUTEL's sudden prominence benefited from launching high-end online programming features. AUTEL was first to implement Wi-Fi wireless updates. Given the high cost of specialized inspections and programming account requirements, AUTEL addresses pain points for many repair shops. Mercedes-Benz and BMW specialty repair shops essentially rely on AUTEL.

XTOOL pioneered twelve special functions including service reset, brake reset, etc., which were unique at the time. Though other diagnostic tools now include them, XTOOL's operations are simpler. Thus XTOOL holds relatively high market share in routine maintenance workshops.

When choosing brands, we should also consider the popularity of new energy vehicles and select diagnostic tools supporting both fuel vehicles and new energy vehicles. Such products offer better cost-effectiveness.
