Depends on the device and personal preference on the temp control. I myself have 2 vapor sharks with the DNA 40 chip and love the TP feature. To me, it's a cooler vape, I've built at a minimum 50 nickel coils and can't get a really warm vape from it. Not complaining, just keep my temp so I don't scorch my cotton.
Not sure how the other temp control devices work with kanthal, I'm with how what Evolv has done with their chips!
Nickel is a little more detail oriented because it's softer and the device demands you have exact connections in order to function correctly. I like it just fine and have had very satisfying results on most of my tanks. Only one that gives me fits is my erlkonigin!
