LR Classic for me. I've trialled Capture 1, On1, Luminar, Exposure X5 and DxO Photolab in a strong and sincere desire to get away from Adobe's sub. Sadly they all fall apart in some way with asset management. Editing side, they're all great, but when it comes to managing and finding photos, they fall down. LR has smart collections, excellent keywording tools, and easy to use customisable filters that allow you to find things easily as well as great sorting options for those who don't have a completely "digital" library (i.e. some images don't have exif data)
