Both are somewhere in the middle of the current generation of clearomizers - more advanced than the Subtank or Arctic, not quite as popular these days as the Crown and TFV4.
Of what you've got, I only have the Arctic - good clouds and a pretty warm vape at 50ish watts, but flavor is kinda muted for me. Being only marginally satisfied, I moved on to the Crown, which I find has even better vapor (and so much airflow I've got to run it partway closed), but I'm still undecided on flavor. This is my first go-round with temp control, though, so I'm not sure if muted flavor is the tank, operator error, TC just not agreeing with me, or the flavors I've got under development still needing tweaking...
