Crap tobacco is such a broad category I wouldn't know where to begin to list all of them...

But as a rule, and this is just me, I'm leery of anything by Sutliff or Lane and anyone else that sells primarily PG soaked Cavendish blends. This includes 'house blends' in glass jars since most of them are re-branded Sutliff or Lane products AFAIK

I've got nothing against a good aromatic... trouble is, good aromatics are hard to find.

As far as good tobacco goes...

As a general rule, I find anything from Dan Tobacco is good - aro or not. Some are better than others but none of their stuff is nasty.

Pretty much any non-aromatic from Peter Stokkebye is good. The aros are hit and miss.

I haven't had a bad blend from G. L. Pease so far.

I haven't had a bad non-aro from Hearth and Home so far.

I haven't had a bad blend from Estoterica so far.

I haven't had a bad blend from Dunhill so far
