Unless you're a mechanic that needs to operate on a wide range of cars, I suggest instead looking for a brand-specific scan tool. Universal scan tools like Launch/Autel/Topdon/Snap-on are good in terms of the wide range of makes they support, but they lack in depth - you may not always get the full feature set especially when it comes to "coding" (aka setting configuration parameters) or anything beyond fault codes, live data streams and actuator tests. Brand-specific scan tools on the other hand only cover their specific brand but generally offer a much deeper set of features.
