You are right that C7 is better than B7.

Although W:G7 looks big, I don't think it's really good. While
B has a weak group he doesn't have a good reducing move in
this area. W:C7 removes B's base, after which B has two
weak groups. (Another at the top.)

Another good move for W is F12, separating the two
dragons and preparing to seal in two stones at E13. I'd
like it if GNU Go would think of moves like that.

But C7 is important because if B captures at A5 then
his group is settled, and B has a large followup at B4.
By contrast after W:C7 the black group needs eyes,
and W is enormously thick.

So C7 looks like the best move to me.
