I have an aerotank and an aerotank mega. The mega leaks like crazy and doesn't provide enough flavor for me. I ordered the upgraded AFC to see if it will fix the leaking, but right now it is shelved.
The regular aerotank is ok, but I've had some leaking issues with it recently. It might be because I was driving long distance over large elevation changes, but I don't know. I don't like rebuilding the new coils, and I've yet to figure out a good way to do so. Right now it is shelved.
I'm vaping on my starter kit evod right now (itaste vv is on the charger) with my own coil build and I'm getting better flavor and vapor than either of my aerotanks at 6-6.5w.
If someone were to ask me, then i would recommend against anything that uses the new kanger coils.
