Luxury Bullseye contains Cavendish. It is much sweeter and much more mild than Escudo. Escudo also contains more perique. In my opinion....they don't resemble each other closely at all with the exception of both being a coin. That said, I enjoy both, but prefer Escudo by a wide margin. It is a more full body tobacco with much more complexity.
This is just one opinion obviously, I'm sure others will chime in.
