|I've never played with Snapseed, so perhaps I shouldn't comment, but if I'm just making global and some limited local adjustments, Lightroom is going to be my tool of choice, given all the workflow advantages it has. If I need more than Lr, then I want the power of Ps. So for me, some of the alternatives, like Snapseed, are non-starters.
Also, FWIW, I'm not sure but I strongly suspect that if you try to work on a RAW file in Snapseed, you are actually working on the large embedded JPEG within that file. I highly doubt that they have written all the RAW conversion routines for the various cameras.
