Gurkhas generally do suck, but seriously, quality tobacco doesn't leave an awful taste.
I purposely stay away from Mexican, Ecuadorean and Honduran tobacco because I get a horrid aftertaste that lasts for a couple days.
On the other hand, one of my favorite cigars is a blend of a bunch of different tobaccos from different countries and they leave an aftertaste that I can't shake for days. The only way to get rid of it is to smoke enough really strong nic puro maduros to mask it.
I enjoy that aftertaste from that particular cigar, so it's not an issue, but I really have to be in the mood for that kind of commitment before I spark one up.
