Mysore is more open-air, not such a dense "crown" as the Goldfinger.
I have old pics of both in my gallery. Mine are actually planted side by side, not for any reason though, just by chance.
I remember Mysore having moderately thin peels so keep that in mind when it gets close to ripening time, they can spoil somewhat fast. Goldfinger has a good thick peel though.
