Stagg is too intense to be a session drinker and I consider it more of a novelty than anything else.
Seriously. Make no mistake, it's a delicious liquid, but when I see pictures of people's collections with 10+ bottles of it, my liver aches for them. If I pour a healthy dram out and finish it within an hour it's a feat, and then I'm totally hammered.

Personally 4R1B is my all time favorite regular offering. It's smooth, balanced, refined and tastes damn good. Stagg is too intense to be a session drinker and I consider it more of a novelty than anything else.
As I have said before I would like to see the "professional" reviewers do blind tastings ... I sense you would see some very different scores and most likely a fair amount less "expertise" exhibited. I find the "hobbyists" blind tasting reviews and scores the most honest given they spend their own money and don't derive benefits of any kind from the beverage industry.
