I have more NGC, then PCGS, 3rd is ANACS, and do have 4 graded by ICG. Personally I would probably buy pre-1934 gold in PCGS, and other than that I would purchase in any of the top three. Personally I'm happy with all the ANACS I have. The four I have from ICG I bought because I like them and wanted them slabbed. I purchased them cheap and they will always be cheap whoever slabs these particular coins. To me is definitely what you are buying that has some bearing on who slabbed it, if slabbed at all. As always to each their own.
Just my opinion, but first that is a very nice coin. From the pictures the grade looks right to me, but I see a lot of red to be a RB. But again a very nice coin.
