He's looking at the 10700, not the 10700k
Better fps, but worse value
Both give you a great gaming experience but your upgrade path on AM4 with a b550 is MUCH more promising. You have a wide open path all the way up to 16+cores plus the ryzen 4000 series. That upgradeability is something you simply can't get from intel, and since your buddy does alot of video encoding it's something that could potentially benefit him in the future. It's unfortunate you are looking at such skewed prices wherever you are from because the $60 dollar difference in msrp (should) make the decision much easier.
go with Intel if your buddy is super concerned with a couple of extra frames here and there, and go with Amd if your buddy values his money and wants his system to be useful to him for longer
