This list would probably change from month to month, but at the moment here are my faves... ...also, what might be mild to me could be stronger for others and vice-versa:

Mild- Cuesta-Rey, Padron 3000, MC #5

Medium- Oliva O, Cabaiguan, Davidoff Gran Cru, Illusione, Padron 64

Full- Camacho Corojo, LFD Double Ligero, JDN Antano
