I like the RP vintage 1990 though I ran out of those a while ago. The rest of the RP line I'm not a fan of; and I do like the summer 08's.
Gurkha has a few I like, the beast, beauty (the large one), titan 1, dragon fires, art deco, platinum reserve, and I do like the red and green dragons. That pretty much sums it up for me when it comes to gurkhas. I've tried many of their new blends as well and haven't been impressed. I should mention I do like the triple maduros though I have noticed that they get a bit "hallow" tasting after a few years, if that makes sense.
