I never used Photoshop that much, but I used to be well versed with Lightroom. So I tried Lightcraft[1] which is their Lightroom clone, and I was disappointed after all that hype. I couldn't get any of my photos to look nice, using the workflows I was used to from Lightroom. It felt cheap, unfinished, and barely usable, also compared to the open source Lightroom alternatives that have been around for a while (e.g. Rawtherapee). I'm willing to change my mind in the future, but at the moment, I don't really get the hype.
