The number 2 Torpedo shape is a challenge for even the most experienced and well trained rollers. So, the quality of the counterfeit is likely to be poor, to say nothing of the quality of the tobacco it is rolled with. First, if it's already in your humidor, I assume you've smoked one. As a rule of thumb, Cuban counterfeits do not have shiny, oily wrappers, uniform shapes, and perfectly finished caps. If so, you may have been had.
Taste is subjective.
No counterfeit cigar correctly reproduces the flavor or consistency of the brand they imitate. There are both well-stocked duty free operations and well established tobacconists in Europe. As a general rule, counterfeiters thrive on markets where there are fewer reliable sources. In 27 years of working and travelling overseas, I never saw or heard of MC Churchills. There is no such thing as a Montecristo Churchill from Cuba.
