On a normal day, it's $150 less than the S10, and today when they're both on sale, the S10e is still about $50 cheaper.It even has the same great camera sensors as the S10, so you're only missing the 2x zoom.

Really, the biggest difference is the screen tech: The S10e does not have a curved screen and its bezels (the black borders around the screen) are a bit wider. However, there is still no notch, so you do get a big beautiful screen, even though it's technically the smallest of the bunch at 5.8 inches.
