I'm 99% positive that the Cohiba maduros are simply Siglos with a maduro wrapper. Meaning I think the Genios is literally a Siglo VI with a different wrapper. If you like the Siglos and like maduro wrappers, these are a must try.
I will say that although I'm a fan of non-Cuban maduros, the Cuban maduros are different. Flavor-wise I think it would be better to compare these with the LE wrappers than with non-Cuban maduro wrappers. They are just ... well, to me they're awesome, but of course to each his own. With age they can develop a syrupy sweetness that is unlike anything I've had in a cigar ... the 2009 LE Magnum 48s are a great example.
As to the cost ... they charge that because they can. No other reason. Sure a maduro wrapper is matured longer, but I don't think it justifies the price. But hey, try them and see if it's worth it to you. And try as many LEs as you can, as I think those wrappers are just as good if not better.
