Which weather forecast is more accurate and saves traffic, weather communication or ink weather?

I used Weather Link for several months and found that its "forecast" is not very accurate (real-time is ok, but it can be updated when I have to watch it); Now it's ok to change to ink weather ~

Traffic? Actually, it's about the same. For surfing the Internet on a monthly basis, it's nothing at all (mine is 5 yuan 30M).
