So I found that using LR for the photographic DAM and processing, especially with the use of VC's etc was far more space efficient. I like that now I can export a file as needed, use it and then delete it from the local disk. If I need it again then I just export it again. That way if you make a change or two to the image you know that you will always be using the latest version. So all my RAWs, and the around 5% of PSD files live only in LR, and that is my main image management and viewing program.
Probably does take a lot less space.
I work in raw (32 bit) as long as I can, and in fact use comp groups to keep different versions of the same image together in one (sometimes huge) PSD file. (Disk drives are cheap). Once done in raw, I open in PS as a Smart Object, which keeps the raw image available for opening, editing, and saving, which will automatically update the image I'm working on. Once done with the images (working in 16 bits) it's saved as a smart object, then Placed (as a linked SO) in a new psd file to be printed.
All this manipulation accomplishes:
1. Always having the 32 bit raw available for updating
2. Images remain in 16 bit and the original color space
3. No file compression (i.e., no jpegs, tiffs, etc)
4. A single final printable modifiable resize-able output product
