I haven't tried Tobacco or USA mix from Dekang, but I really like the 555. The only thing that may help you in your choice is that the 555 has a Hazelnut finish. Of my friends that have tried my juices, they like the 555 the best. But they all taste Hazelnut.
I have another 555 variant from another vendor and it had the horrid chemical taste. I don't get that from Dekang 555.
