Ping vs 2020

I am soon to have a upgrade for my animas 2020. I wasn’t too sure the difference between the 2020 and the ping. Can someone pleAse explain?

For one thing, on your 2020 you have the food data on the pump. The Ping system has the food data in the meter, not on the pump. You’re gaining the meter which communicates with the pump.
Something you may or may not care about.
