If you can afford to spend the money on S20+ there is no reason to look at S20 FE. The only advantage I can see of FE over Plus is even though battery is same, FE has a lower resolution display and so should last you longer than the other. Or maybe if you like flat screens better than curved ones, you can go for S20 FE. The main advantage of S20 FE is the 10k or so money you save over the Plus model without losing much of the features.
