Well, the iPhone SE has really poor specs compared to an Android of the same price IMO. The SoC is up to date, but the screen is only LCD, the bezels are huge (the screen to body ratio is very low) and the camera is only adequate.
Basically you're buying a 4-year-old phone with a modern SoC in it :) I don't think that is worth the price they are asking. I paid the same (440 euro) for my S8 3 years ago (it was out a bit over a year), and it already had a beautiful AMOLED screen, high screen to body ratio, and in particular DeX which I can't really do without anymore. And it's still fast enough now. I upgraded to that from my iPhone 6 which was becoming way too slow at that point (note: iOS 12 did fix this somewhat but by that time I had already had enough of it). Overall, the S8 aged better for me than the iPhone 6 did.
Compared to what you can get from Apple now vs the Android vendors, Apple is only ahead in terms of SoC when you're looking in the same price bracket. But that's not the only spec that matters.
