IMVHO, there is a lot of hype, overpricing, and general overrating of the Opus X line....Generally speaking.
If you take some time to look into what a time consuming, thoughtful, and intricate process is involved in just creating the wrapper (just the wrapper, mind you!!) for a T52, then you will appreciate what a bargain each cigar is; let alone the exceptional quality.
As far as overall experience (ie craftsmanship, burning qualities, enjoyability), I think the T52 is better than the Opus X...Not better by leaps and bounds, but better.
For Dominican cigars, Opus X is a household name...Even for households that contain no cigar smokers. Why? Lots of hype, practically unattainable price points, etc. The question is, at the end of the day does the quality really match all that price and hype? I personally don't think so at all.
Give me a T52 over an X any day.
