In a busy studio I cannot live without LR. I shoot several products on any given day, tethered to my PC, and have any one of several marketing managers in the room with me. I am constantly going from capture to edit until I hit the shot that works for them. Using Bridge and PS combination would cost me a penalty in time and productivity. I could care less about minute issues with noise or pixel peeping priorities. In regards to database and file management. I work with two LR databases. That is, I open a fresh database just for the current project (it's lightning fast that way). Once done, I dump the rejects and import the keepers to a master LR database. I then upload the same keepers to our server based cumulus DAM, which plays well with DNGs and uses the same keywords. It's then up to the designers down south and in Europe that pull them down, and they use the Bridge/PS combination. They absolutely love it. That is, they can tweak the negative to their own result via ACR, and with me using LR, I can literally have the job shot and uploaded within the hour.
Right tool for the job.
