It's personal choice, each to their own, but it's not helpful to fob people off telling them to show % and ignore the discrepancy rather than answer the question as if its a superior thing to do.
It's not superior in any personal way. Clearly people will choose what works for them ..but.. percentage is actually superior as an indicator of reality! If the battery indicator says 50% then you know you have 50% of your battery remaining! If it indicates 150 miles it doesn't tell you how far you can drive until empty because it could be 90 miles you have in reality. The only way you can make a miles setting work for yourself is if you are doing a calculation in your head because you realise 150 is not realistic ... so for many of us (since you have to calculate it anyway) choose the consistent indicator of reality i.e. percentage. That means that your calculations at least have a consistent and reliable starting point.
