You can buy just about any tank that uses SS coils and use those in tc.
MOST tanks that use premade coils have a SS option.
As to which is best, Thag would depend on your vape style.
If you’re vaping a pen, I would venture to guess you’re vaping mtl. If you are, than I would start with a nautilus; and use the aspire bcc SS COILS.
For a mod, the dna has been the regarded as the best you can buy.
If a dna is out of your price range, take a look at the voopoo drag. The gene chip has been highly regarded as a great, more affordable
Option for tc.
For dna mods, I would start looking at either thinkvape or lostvape. Both make some great higher quality mods
