I’ve been a big fan of DxO for many years. I don’t need PureRAW, I use the full DxO PhotoLab. The NR is great, but so are the geometric corrections. With the RF 14-35, I get an FoV of ~13.5mm with DxO, whereas Adobe gives just very slightly wider than 14mm (a few pixels), and Canon DPP gives just very slightly narrower than 14mm (all with the EF 11-24 at 14mm as a benchmark).
