Is GDP deflator or CPI better?

Does CPI adjust for quality?
The CPI uses hedonic quality adjustments in item categories that tend to experience a high degree of quality change either due to seasonal changes, as in apparel items, or because of innovative improvements and technological changes, as in consumer appliances and electronics.
What deflated sales?
Purpose of deflation Changes in the value of sales collected at current prices (i.e. at the time the sales took place) may be attributable to changes in prices or to changes in quantities sold, or to both. This process is known as deflation.
Why is CPI not accurate?
In other words, the CPI doesn’t measure changes in consumer prices, rather it measures the cost-of-living. So if prices rise and consumers substitute products, the CPI formula could hold a bias that doesn’t report rising prices. Not a very accurate way to measure inflation.
