Of course, China 6 is better. If you are buying a car now and don't plan to use it for a long time, you can opt for a China 5 model, as China 5 cars are currently cheaper. However, if you intend to use the car for an extended period, it's better to choose a China 6 model. Here is an introduction to the China 5 and China 6 emission standards: China 5 Emission Standard: The carbon monoxide emissions per kilometer driven must not exceed 1000 milligrams; non-methane hydrocarbon emissions per kilometer driven must not exceed 68 milligrams; nitrogen oxide emissions per kilometer driven must not exceed 60 milligrams; and PM (particulate matter) emissions per kilometer driven must not exceed 4.5 milligrams. China 6 Emission Standard: The carbon monoxide emissions per kilometer driven are limited to 500 milligrams; nitrogen oxide emissions per kilometer driven are limited to 35 milligrams; PM emissions per kilometer driven are limited to 3 milligrams; and non-methane hydrocarbon emissions per kilometer driven are limited to 35 milligrams. Additionally, the testing cycles differ, comprehensively assessing vehicle emissions during cold starts, acceleration and deceleration, and high-speed, high-load conditions. This covers a broader range of engine operating conditions and imposes higher requirements on vehicle emission control performance.

China VI (National VI) emission standards are far superior in terms of environmental protection. They significantly reduce harmful emissions such as nitrogen oxides and particulate matter, which is particularly beneficial for improving air quality, especially in large cities prone to frequent smog. The China VI standards require new vehicles to be equipped with more advanced catalytic converters and sensors. Although the initial purchase cost might be higher, they offer better fuel efficiency, making them more economical in the long run. Having driven both China V and China VI vehicles, I find the lower emissions of China VI models more reassuring during stop-and-go commutes, with noticeably fresher air quality. As environmental policies tighten, more cities are restricting China V vehicles from entering urban areas, so opting for China VI helps avoid such inconveniences. If you prioritize health and urban sustainability, China VI is undoubtedly the better choice.

From the perspective of purchasing a car and budgeting, I find the China 5 standard more appealing if you're on a tight budget. China 5 vehicles are usually tens of thousands cheaper, with lower insurance and tax costs, and they remain quite popular in the used car market. However, in the long run, China 6 models offer more stable maintenance expenses, as their engine designs are more optimized, reducing issues like carbon buildup. When helping a friend choose a car, I noticed that China 5 parts are cheaper and easier to replace. Yet, many regions now incentivize China 6 with higher subsidies for new cars. Overall, for short-term savings, go with China 5; for durability and resale value, opt for China 6.

In daily use, China VI vehicles provide a smoother and more seamless experience for me. They offer quicker power response, with no sluggishness during starts whether on highways or in urban areas, and higher fuel efficiency means fewer trips to the gas station. While China V models are stable, they are a bit outdated, sometimes emitting black smoke during cold starts and consuming more fuel. Having driven for many years, I find the OBD system introduced in China VI vehicles more user-friendly, with fewer instances of malfunction indicator lights turning on unnecessarily. In terms of maintenance, China V models are easier to find someone to repair due to their simpler technology. When driving in the city, China VI vehicles face no travel restrictions, making life a bit easier. Overall, for convenience and hassle-free driving, China VI is the preferred choice.
