I don't think the Kanger Subtanks offer as good a vape as the Crown.
If you really want to vape at 60w, the issue is maybe more complicated. I don't see the Subtanks getting up to 60w but then again I've only vaped one tank at 60w and it was a cheap Eleaf tank taken off the iJust2.
My vaping stops well short of 50w although I have vaped at much higher for interest.
My Subtanks are only used at low wattage and they shine between 15 and 30 watts especially with the RBA .
The original Crown gets the best reviews for a flavor tank i have ever seen , it's incredible but the coils are superb and they last and last .
The Crown II got a bad rap solely due to the bad initial coils it came with but i can tell you with certainty the Crown II these days and the one i ordered from Ecig.com comes with some of the best coils i have ever used.
No leaks whatsoever and flavor is off the charts . I actually bought the Crown II before i got the original Crown and from all the positive reviews i found it hard to believe it could be better than the Crown II and to me it's not , about equal actually .
The Crown II takes the Rafale RBA kit , original Crown takes it's own RBA kit.
I do find it very disappointing when reviewers judge how good a tank is based on if the coils they bought for it are satisfactory or not , you are always going to get a few dud coils here and there.
I judge a tank on how well it performs with the RBA .
