All 6 of my stocked liters are MFS because they were cheapest and at least a few people in the forums said they couldn't taste anything. Dad hasn't said a thing about his having a taste, just that his favorite flavor is "perfect." on his first DIY attempt. His friend he's been buying juice for said he "nailed it" with their cin bun flavor. So neither of the first time DIY juice guys had a clue.
I'm going to be a first time DIY guy. I don't think that I'll really notice a taste unless you all keep talking about it and I'm looking for it.

Either way, to me it's going to be the taste of tax free juice, and it's going to taste wonderful.
