I tried the 8 specific characters that you mentioned (the endpoints of the ranges) with emacs -Q, and found that in my environment Symbola looked way better with U+1F600, U+1F64F, U+1F100 (where older Emacs just displays hex codes in boxes), that Symbola looks a bit worse with U+2E00 and U+20A0 (where older Emacs uses FreeSerif which better matches the FreeSerif characters elsewhere in the buffer), and that both fonts look bad (hex boxes) with U+1F1FFF, U+2E7F, U+20CF (as they're unassigned).
