Most people hear "LFP lasts longer" and stop there. This video breaks down why that is only part of the story. NMC holds up better in cold weather. LFP can be charged to 100% daily without stress. And an LFP car with 420 km of rated range charged to full may give you more usable daily range than a 500 km NMC car you keep between 20 and 80 percent. Factor in insurance risk, replacement costs, and resale psychology, and the "best" battery depends entirely on how you actually use your car.
