I also prefer db1, but it just depends on your tastes. The db1 reminds me of tobacco with a hint of ry4. I'm waiting on a 30ml of it right now.
I don't care for the db2, but that's just me. The db2 is not sweet at all, and i distinctly taste peppers (the first time it reminded me of nacho cheese until I figured out it was more like peppers
) Others really like the db2 and probably think I'm crazy talking about peppers and cheese lol
A lot of people love 555, but I think it tastes like an ashtray, it's all a matter of personal taste. I would try a sampler of each first, I never buy a 30ml unless I have sampled it, but that might just be me being cheap.
