the T110 is strong, but I think they mellowed a bit fast... don't know why... maybe it's just me. The OR T110 I had, was fantastic. Smoked great and tasted great, but did not hit me with strength, just loads of flavors.
The Cain F is significantly stronger, but I find it very balanced. The flavors are all there, and the cigar burns great. This one will hit you hard, and you will feel it.
The Double Ligero is even stronger... I don't find it to be as refined as the other 2, but it does have a much stronger kick. It has some good flavors, but I find it too unbalanced for my pallet...
Remember, some cigars hit you in a different way than it does another person... so it really comes down to which one is stronger to you.
