Not necessarily. One nice thing about this report is they take into account the low statistics in some of their drive models and represent that as confidence intervals. If you look at the second table, 8TB HGST and 5TB Toshiba have a wide uncertainty due to them having tested fewer of these drives so far. Their data can not yet tell us if the AFR for these drives are significantly different from others. They do have many of the smaller 4TB HGST and so have tight uncertainty on them and they are indeed low AFR. So if that size is suitable then it's a no brainer choice. But, if bigger capacities are needed and looking at the high confidence limit column, the 6TB and 8TB Seagate models are safer bets.
