In my short time gaping--I have tried a LOT of different juice. I will say that I like strong flavors and so far have been disappointed with many.
I ordered a number of flavors from MBV because of being able to add the extra shots of flavor. All of them I have tried so far have been a big disappointment--to be fair I am now letting them steep, but even the batch that is a month old and steeped for at least that long are dull and muted IMO.
Next I ordered the sampler from Alice In Vapeland--those juices are indeed more complex--but IMO not strong enough for me. There have been a couple that have been pleasant--but nothing I would go back and order larger sizes.
I also have a number of flavors from Ahlusion--they too are steeping as right out of the mailbox--very little flavor and very chemical. Maybe I will like them when they steep awhile---so the verdict is not completely in on those either.
One of my very favorite liquids is Absinthe from St. Louis Vapors--it is strong and I love it. I do like the anise flavor so I did order Pluid and it is now in my rotation daily!! It is anise based but has some citrus notes that are subtle and wonderful. I just ordered 3 more 30ml bottles and will keep it on hand always!!
I think at this point I have been happier with Halo--Johnson Creek and Five Pawns due to their consistency in flavor and not having to steep months and months for the flavor to show up. These are all blended well and although I do prefer some of the flavors over others--all are relatively good and won't be wasted.
I have not yet tried Boba's or Gorilla Juice. I have tried some of the Provape juice and I ordered their strong flavors--all have been very good.
I know that I have ordered a lot as of now and I am sure that I will be able to mix some of the less flavorful with others and might come up with something wonderful that way

.
Good luck on your quest to find the right thing that will work for you! Just thought I would share some of my experience--and I agree with others--taste is very subjective.
