Well theres one word that makes the new dna boards (c boards) my first choice and thats replay.
Yes i am bias because thats all i use, except for my squonk.
Im not like @Sprkslfly very technical and can base my knowledge on that. I can only make this suggestion based on my own user experience.
I personally dont care about how it works or why, as long as it does. If thats good enough, then keep reading
The gene chip doesnt compare at all. Its a good chip, back in the day and did have a lot of features that were above average to that time.
Nowadays with the products out there, it falls in my opinion just into the generic chip category. Based on tc, it would fall more into the mediocre categorie, since voopoo cant seem to get rid of their stupid mindset and locking the devices at 80w in tc. Therefore garbage and their customer service sucks even more.
Lately theres also lots of issues with the newer products of voopoo, seems after the old drag (not the resin editions, these fall already into the new product category) the quality control department was layed off and they abandoned that department, because in easy words, just dont bother with them.
Fsk, i assume we are talking about the old mods that were designed by hohmtech? I still use one to this day, and always would recommend them, if you find it at a good price. If you need to pay $80+ (the old nostalgist price) then dont bother, because while its good especially in tc, at that price you nearly can get a new dna.
Yihi, well its just like in the real world, you will find people telling you that pepsi is better than coca cola and vice versa. Thats how i feel about it too, tried a yihi device, just not the new sx class, that might be different. And couldnt find anything bad with it, tc worked great (only way i used to vape at that time) not much hassle, no setting up via pc needed etc.
And i mention it now again, because i love mine so much lol, purchased a dna 250c and remember the only word you ever need is, replay!
If you have the funds, do some research on both of course, but i highly recommend a dna with c board!
