The red (Havana VI) and brown (Cabinet) tats are very different from one another. I like both, but the browns are some of my overall favorites (my favorite NCs for sure). One important note is the blend in almost every vitola in the brown label is different form the next (if this is wrong someone correct me). The reds are great too just not as strong or complex in my opinion but still damn fine smokes.
Here is a link to Moki's site that has a lot of good info on them
