I was an iPhone user from the 3GS until my 6+ finally bit the bullet, and refused to give up the headphone jack. I genuinely love the iPhone and MacBooks.
I've been using the Galaxy S8+ since launch. And the Note 8 is, by any definition, as good or better than the iPhone X.
If you haven't used a Samsung phone lately, go try an S8 or Note 8. They have "the package" down. It just works, and doesn't require a PC or iTunes. I don't care about speeds and feeds. I care about how the phone operates on a daily basis.
iPhone X has FaceID and pin# to login.
Samsung has face, retina, touch and pin options.
The Note 8 is cheaper, with expandable storage, a higher density display (with the same white balance adjustment), stylus, side-by-side applications, a headphone jack, samsung pay, and NFC.
(There are probably many more, but these are things I use on a daily basis, or very frequently in the real world)
The iPhone has iMessage and Facetime.
Seriously, it's worth a sniff of the other side of the pond. It took me 2 hours to transfer everything - contacts, media, apps. And another day to get the UI sorted (there's even an "ios mode" for the launcher that acts almost exactly like the ios interface). I still use an iphone often for work and it's honestly painful going back to it, there are so many little annoying papercut experiences.
