Samsung Galaxy S10, S10+, or S20?

I'm unsure about buying food. Since my S7 is gone, I have to deal with the Huawei P20 Light. I urgently need a new one, this P20 drives me crazy. Terrible screen and the photos felt like 10 years ago, I don't have to start with the colors.

Which Galaxy would you recommend to me? Is there a big difference between the three above? What is exactly different?

In Switzerland S10 128gb 579.-, the S20 899.-

I don't always need the latest and most expensive, but I use my cell phone very often for photos.

I would recommend Xiaomi rather than Samsung or other bells and whistles because the price-performance ratio of Xiaomi is simply perfecto ala perfecto 😄
