Users of DxO PhotoLab ELITE Edition already have access to DeepPRIME and DeepPRIME XD, making additional software unnecessary unless you are a Fuji photographer looking to utilize the DeepPRIME XD3 X-Trans beta denoising feature.
However, batch processing with the option to shuffle the order of images and priority within a batch and custom naming conventions to each batch of images for faster identification later in your workflow are strong arguments for purchasing DxO PureRAW.
For users of DxO PhotoLab ESSENTIAL Edition, DxO PureRAW will allow you to use the newest DxO Labs denoising algorithm, but it may be more beneficial to you to just upgrade in your customer account to DxO PhotoLab 8 ELITE Edition.
