How many flavor shots did you get?
Some folks really like MBV tobaccos, some don't. The MBV tobaccos that I like need a *really* long steep - even with speed steeping, mine have still needed several weeks to get to good.
Cake (Yellow) - that chemical flavor means it could use a couple of days of "pop the cap and the drip tip off, squish the bottle until the air in it has changed out, then put the caps back on and shake". That will usually kill the chemical taste.
(Haven't tried the others on your list, so I can't comment on them.)
I do have a couple of bottles of MBV
juice that still taste horrid to me - but that's a very, very small percentage of the ones I own. (I'm looking at you, pineapple upside down cake.)
But, ultimately, the right
juice for you is juice that you like. There's no requirement to love juice from any particular vendor.
