The only things I find consistently a let down are Rocky Patel and Gurkha.
To Bradleys point, Viaje are right in the middle for me. When they get it right, they nail it. I have had some of them that I would NEVER touch again as well. Mostly on the good side, but they can be a frustrating company to me.
Oliva can be like that to a point for me. The regular Oliva stuff is pretty underwhelming for me, but I love the Serie V and Maduro. Oddly, I didn't like the Melanio, but loved the Melanio Maduro. But Oliva is never construction, it is just my flavor preferences.
Crowned Heads and RomaCraft are my go-to brands, and always love Tatuaje, Liga Privada (most DE that is not the infused or cheap crap), Illusione, Panacea, so many others that never let me down.
