Everyone keeps comparing the 12 to 12 Pro at 128GB, and everyone is right to point out the bad value there.
But at base price and not needing more than 64GB, the iPhone 12 is a fine deal. Still diminished value due to the increased price, yes, but still a fine deal if a user smartly utilizes iCloud, streams all their media, and simply doesn’t need more than 64GB. $200 difference is still $200 nonetheless, and for many, this is a better option still.
Knowing how you use your phone and what model is best suited for your own usage is key to finding value in each model in the lineup.
