I am using Bridge at the moment as it will load all raw files...
What product of FastStone is the best, you think?

I've yet to find one that does all things I need. I resisted View NX for ages, then found the star rating was useful in culling my initial shots though other parts of it weren't good. FastStone is quicker for me and gives a good instant zoom, but (when I last looked) didn't allow a star rating. Sigh...
Though I've got the Photog's CC subscription I don't do enough PP to need all the extra tools it offers (maybe that shows in my images....). So after a few months persisting with it, I found myself going back to NX2. Luckily that still supports my camera body.
Finally, you mentioned printing John.
Until Adobe improved PS, I used to find a tool called Qimage quite useful. Although I now rarely print at home, I often resize images to send to an online printer. There were several features in Qimage that seemed useful (though Adobe may now cover them all).
