There are people in this very thread who are one million times more qualified to opine on the technical aspects of temperature control vaping than myself. I own that right off the bat.
That said, what matters to me is how good the vape is. I have just enough technical aptitude in researching tc to have assumed all along that the number I see on my screen is not strictly representative of the actual objectively measured temperature of the coils.
To me personally, "good tc" means it hits consistently throughout the pull and doesn't burn my wicking if it gets dry. Whether the actual coil temp matches the setting is almost irrelevant, though it would be a bonus.
That may be a low bar, but it works for me and I prefer it in most cases with regulated devices over straight power. There IS a noticeable difference.
i love my DNA devices. They do great tc (by my above standard) and replay actually works as advertised in my experience. How it does that will probably continue to be debated and I LOVE those discussions, but in the meantime, I just know that it does
I also have a few YIHI devices, including an SX Mini G-Class, which I also love. I have found that the "rattlesnaking" on YIHI boards can be almost completely eliminated, even with their budget chips, with some tweaking, though the J series is clearly superior.
I haven't made up my mind about whether I think this is because Evolv circuits are just more accurate or if maybe it's because YIHI circuits are actually more accurate and thus display more sensitivity to the fine properties of the specific wire they see at the moment. I do understand that Evolv and YIHI use different methods of achieving their regulation of the wattage sent to the coils in tc.
Dicodes is just WAAAAAY outta my price range. It's not a matter of being a cheapskate, I don't have it. Unless some unfortunate soul were trying to dump one stupid cheap, I'll never own one.
EDIT: I thought I should throw in here that I have never paid retail price for the nicer stuff I own. Some may rightly say to themselves:
"Wait a minute. Evolv and YIHI devices are not exactly dirt cheap either."
That's true, but I paid 80 bucks each for my Paranormal 250C and SX Mini G-Class for instance. Both in practically new condition and that was pushin it.

I pride myself on being a patient and frugal shopper, mostly because I don't have any choice.
