No issues with the review to me, again I will argue against Samsung's update schedule being on point. But maybe that is just me being bitter that I will likely receive the S10 Plus before I get Pie on my note.
They’re on point with security patches, which makes a difference for businesses and organizations that rely on “secure” phones. Knox is also there in addition. In terms of major OS updates, Samsung is really slow. But we are at a point where major OS updates won’t necessarily make or break the user experience. If you prefer timely major OS updates, iPhone/Pixel/OnePlus will cater to that.
