would someone compare/contrast Costuluto Genovese & C. Fiorentino?

[stormymater]

I get HOT & HUMID summers & would love a mater that capitalizes on these climatic realities. I planned on getting C. Genovese but thought I'd get some advice from more experienced tomato folks before pulling the trigger. Thank you - I have been here just a short while but have learned a lot I'm putting into practice in the insectarium I call the garden out back.
