There is no single application that provides me with the best culling, best image Raw file conversion, best image editing, and best file management. Lightroom is like the Swiss Army knife that has many tools but none are particularly good. It is like the old Japanese saying "he has many knives, none sharp".
Lightroom has become much better over the years with regard to image processing but it still is designed for a single user with a single computer and for this reason I have sought other applications. I use FastRawViewer for culling, NX Studio and ACR for file conversion, Photoshop and Affinity for image editing, and iMatch for DAM. One key advantage of this approach is that I can use the iMatch for my audio and video files as well as my still image files.
