Apologies to Mr Teatime, I know it's just his style and he didn't mean to come over as I have suggested. I have spent a lot of time trying to perfect TC vaping and know that it is far from dogwank, but it is different, that's for sure.
I think there are a lot of aspects to discuss on the advantages and disadvantages of kanthal and TC vaping. Kanthal is always going to hit harder, or at least appear to hit harder than TC coils simply because by its very nature you are setting limits with a TC set up. That is one aspect that probably could be considered as fact.
Preventing dry hits is very much a side benefit of TC vaping. Any experienced vaper can avoid those most of the time, although as Pbusardo often points out, if you are using a stainless Kayfun tank, you don't have to worry about how low your juice is getting - your vape just becomes anaemic and you twig that it's time to juice up, which is kinda nice. Mind you, I don't believe people who say they NEVER get dry hits unless they are exclusively dripping. If you use tanks, you're going to get a dry hit at some point so don't bullshit a bullshitter.
For me, one of the best advantages to TC vaping is being able to get quite different vape experiences from the same coil. Maybe in the morning I want a little less dense vapour than I do later in the day. Sometimes I want a hot vape and sometimes I want it a little cooler and with Tc I can get that without having to change coils to achieve it. Different juices also taste better at different temperatures and again, TC vaping means you don't have to change the Ohms of your coil to suit - just change the temp!
There are many more advantages and disadvantages to each, but this post is already too long and dull.
