I watched this video. I don't think he ripped the s10. He actually gave it a good review, he even said buy it at the end. The things he didn't like about it were about the same he didn't like about the note 9. He did say the upgrade to the s10 from a note 9 or s9 was not worth it for what you gain. He said the same thing about upgrading to the note 9 from the note 8 or s8. He is correct about that, upgrading yearly does not gain you much for the price. He said the same thing about the price being to high on the note 9. As far as no Iris scanner, that's a personal deal, like he said, if you're concerned with actual secured phone you need to using pattern unlock or PIN unlock.
I have the s10+, the display is better, it is faster then the note 9, I like the front FPS, I personally like the size better, the speakers are amazing, that's off the top of my head, but unless you like having new tech like I do, the upgrade is a little steep, but that can be said about any yearly upgrade. In reality, upgrading every 2 years is what we should be doing, but it's an addiction for the tech love people on here, and if you are a tech love person, the s10 won't disappoint, even if the FPS gives you issues, there's work arounds for that.
