It takes no more effort to open a RAW file and edit it and save it as in the open TIFF format than it does to save it to the proprietary PSD format. No difference in batch processing time with an action either. File sizes are equivalent with the two formats so no benefit to PSD in terms of file handling, storage, and archiving.
With Adobe continuing to buy up their competitors and shut them down and now forcing people to rent their software and use it online, I am moving away from all Adobe products over time. The transition is much easier with all my files in RAW, TIFF, and JPEG format.
I have been using mostly TIFF as all the labs, printers, and graphics designers, and all the people overseas that I work with use TIFF and none use PSD format files. Initially I would have RAW, PSD, TIFF, and JPEG versions of images and it was crazy. At least I was never suckered into the Adobe DNG format which provides no advantages at all.
