Comparing cell arrays of symbolic variables

I'd like to be able to compare two arrays, each consisting of symbolic variables. In particular I'd like to be able to run setdiff on them. But setdiff appears not to work for symbolic arrays, as the example illustrates
syms a b c
G{1} = {a,b,c}
G{2} = {a,b}
setdiff(G{1},G{2})
Is there an alternative way of accomplishing what setdiff should be able to accomplish?
Thanks!

isequal(G{1},G{2})
The above code will return if true and 0 otherwise.

You do not have symbolic arrays to take the set difference of. {a,b,c} is a cell array each element of which contains one symbol. The symbolic array form would be
G{1} = [a, b, c];
