Okay, after going thru every page of this thread, and keeping a scorecard of favorable mentions, I compiled a list for my inaugural DIY Juice order. A month ago, I got:
HS: Tab, Gold & Silver
INW: TA Garuda, Flue Cured, DNB
SC: Cohiba
FA: 7 Leaves, Desert Ship (meant to get Hangsen's)
Went max VG on all of them with VG based nic. Only PG in flavorings.
HS Tab (7%)
Pretty good - solid tobacco, a little nutty, all around a nice vape. Deep, smooth flavor, not overly sweet. Not much change in a month of steeping, shake 'n vape was great.
HS Gold & Silver (7%)
My favorite, initially. This was really a great cigalike taste. Not a deep, rich flavor, but has real high notes, the spiciness that real tobacco has, and is well rounded. The most satisfying hits I've had since smoking. Made me feel like I'd just smoked one of my Dad's unfiltered Lucky Strikes. Great throat hit and mouth feel.
INW TA Garuda, Cohiba, DNB
Really got this to try a Cohiba/Garuda/DNB recipe recommended by DannyV, in 2/2/2% mix. This didn't come out as flavorful as I'd have liked, was nice but kind of bland, when I'd expected a more robust cigar flavor. I've since boosted the Garuda, and lettin it steep. As a standalone, I really like the Garuda- has a really bright, fresh flavor, but is kind of one dimensional. Cohiba by itself just wasn't very interesting. Just an OK flavor. The DNB, they say is to add an "ashy" character. It's not really ashy, but I know what they mean - it's easier to type than "OMG- I'm actually exhaling smoke!" It really does add that effect. It adds a mouthfeel much like chocolate - not that it's sweet, or tastes like chocolate, but totally saturates the taste buds in the way that a fine chocolate does. Unfortunately, it has only the "bass" notes, and kind of mutes the bright flavors of some of the other tobaccos. But it's something that tobacco loving vapers need to try - just use it sparingly.
FA Desert Ship (2.5%)
Probably has the best aroma out of the bunch. Smells awesome, very savory. Unfortunately, I've found I just don't like sweet vapes at all. First hit is nice, but after a handful of hits, I've got to have something else. Tried fresh and steeped, and got the same result. It was better after steeping, as the sharp caramel flavor mellowed, and allowed more tobacco to come thru, but still too sweet for me. I might pour it in my wife's candles, though - still love the aroma!
FA 7 Leaves (3%)
Expected it to be a nice mix of various tobacco's, and saw many people loved it when reading this thread. But it reeked of anise/licorice when I opened it. I hate licorice. Found out that doesn't steep out. Fail. Completely.
INW Flue Cured (2%)
Like the TA Garuda, has mostly high notes. Very mild, smooth tobacco, with hay/straw flavor. Has a natural, light sweetness, without tasting sweetened, if that makes sense. Initially, I thought it was nice, but very one dimensional - kind of boring. But I kept coming back to it, and using it to top off tanks of the others when I got bored with them. Overall, this and G&S are my favorites - and they play very well together - I tank mix them often. Funny that I like the flue cured so much, because I went in thinking that I'd need bold, robust kind of flavors to satisfy me.
Hope this helps someone. And my next order will include a Virginia, Elder Captain, Gold Ducat. Unless anyone can tell me that these might be too sweet? Would love to have other recommendations of non-sweet tobaccos.
