I've only watched a few minutes and I like this. It took me much longer to find problems than Claiborne; the first two steps I watched of Claiborne were bad to me, and that was one of his highlights on draft day. Jones's feet aren't sluggish and he can move with crossers = he's going to play at least 600 snaps.
I don't know about his vision, though. I've noticed him moving his head to the backfield like he doesn't see/trust his peripherals; that reaction time to get eyes back to the WR after the snap matters. It's more of a body language thing rather than evidence. Can't see what things look like downfield on broadcasts so can't confirm either.
I don't like his tackling as a safety, it's more acceptable as a corner. He'd hardly get stops short of the first as a safety trying like that.
