Wow factor? Dan tobacco's Holly Non Plus Ultra definitely has wow factor. Just not in a good way.
As for blends that will not leave you longing for death, I can think of a few.
MacBaren - St Bruno - Even though it's a Danish clone and inferior to the Ogden's original it's still pretty good.
Gawith - Full Virginia Flake and Full Virginia Plug - getting a bit more variable in quality, but still not too bad
Gawith - St James Flake and Plug - really get some WOW after 7 years in a jar
Gawith - Best Brown Flake - If it isn't moldy on arrival it's a great smoke, especially with some years on it.
A&C Petersen - Escudo - no, not the crap that STG produces, the old stuff, 2006 and before. The new stuff isn't Escudo
McClelland - 40th Anniversary - If you love matured Red Virginia, and who doesn't except for slobbering morons, this is one of the best Reds McClelland produced before they went tits up
McClelland 2015 - Their bulk Va/Per that's better than almost every onter Va/Per on the market today - also out of production, so good luck!
Esoterica - Dunbar, Dorchester, Tilbury - These feature fine quality Virginias with an Apricot topping, really they're aromatics, but apo;gosts claim they're only "semi" aromatics, whatever that's supposed to mean. Naturally, they're hard to find for some and not so ard to find for some.
HU - Director's Cut, 5th Anniversary Blend, Edward G, Makhuwa - Look for 2017 or earlier, before K&K started adulterating the blends to save a few pennies. However, Director's Cut may be back to its formal self.
Rattray's - HOTW, Marlin Flake - again, look for 2016 or earlier because K&K...well, you know...
RO Perique Series GP-11 - a spectacular Va/Per long out of production
GL Pease - Ravens Wing, Bohemian Scandal, Renaissance - all long out of production but extraordinary blends.
Ardath - State Express London Mixture - best of the best for a Oriental/Latakia blend - hasn't been made since the 1980's (?)
MacBaren - Capstan Blue - still pretty good, even if it's a Danish clone
Savinelli - Doblone d'Oro - want to smoke something that actually tastes like real Three Nuns? This is it.
C&D - Yorktown - A great all day smoke
GL Pease - Haddo's Delight, Telegraph Hill, Union Square, Fillmore, Stratford
In my humble opinion, if you can find 2016 or earlier on pretty much anything, you stand a better chance of getting a better version from when hand picking leaf was much more common and before dark fired started being subbed for Perique in order to save a few bucks.
