Easy choice for me!!
Mag 46 -- you'll want 3-years of age or so for these to really shine, but they are outstanding. Medium-full bodied, just tons of flavors (earthy, woody, coffee) with plenty of spicy/peppery notes for a Cuban.
RASS -- delicious. Unique floral and fruit profile, creamy thick smoke. The 2010s are just off the charts good.
I think that PSD4s can be great, but I've had some inconsistency issues. Haven't had any from 2010-on, though. Monte #4s are the best selling cigars in the world, and are therefore mass-produced in Cuba. If you get a level 7 roller who does your box, you're in for some great sticks. But it's more likely you'll get a level 1 or 2 who doesn't know what they're doing.
