Flavorwise, I am finding them very close. The advantage of the KM3 for me is that I can see my juice level. That's what it was about drippers that I never liked. I could never see how much juice I had left. The other thing is that while the Achilles and KM3 have similar capacities, I am not refilling my KM3 as much as I was the Achilles. Now some of that may be due to the fact that I wasn't running the Achilles down as far as I do the KM3, but nonetheless I am not filling as much with the KM3. One other notable advantage with the KM3 over my Achilles is the atomizer does not get as hot. I'd go to chaining the Achilles and that dude would get very warm. The KM3 is less severe. Even with plastic drip tips the Achilles was still warm.Ok I have been really wanting to ask this and since both @StealthyTX and @Bronze are present it is time.
You both have Achilles, what does the KF3 offer or do better than Achilles?
