I've had several fresh and I found them to be lacking. Didn't live up to the hype in my book at all, and I, like you, was dumbfounded as to how a cigar so highly rated an raved about could blow donkey balls between the bland flavors and burn issues galore. I eventually learned that Opus cigars require rest of at least one year and many people don't smoke them before 2 or 3 years to get them to really shine. I've had aged Opus and I must say the difference between a fresh one and aged one is night and day. Better and more nuanced flavors and the burn issues I've had with fresh ones dissipate for the most part. And therein is the rub. A great tasting, though super expensive cigar that requires in many cases multiple years of aging. There are plenty of good Cubans that I could procure for far less cost per stick then any Opus product and the downtime would be the same. There are obviously plenty of great DE and Tat sticks that I can light up and enjoy now for the same price or slightly less.
Having said that, in my experience an aged Opus is a thing of beauty and something you should try at least once. If you have the space (and the budget) pick up a few and forget about them for a year or 2. When you revisit them I'm sure you'll feel differently. Other cigars that are similar in being NCs that require downtime but are worth it would be the Ashton ESG and VSG. If I'm not mistaken both are also made by Fuente so no surprise that they need rest I suppose. Anejo's are the same way with many people not lighting one up for a minimum of 3 years and I've seen a few people on the board state that they wait 5.
