I understand that one has less resistance. Yet would you get the same vape doing the .5 at around 30 watts and the 1.2 around 25 watts? I guess I really just want to know how you would choose one if you are vaping it on a VW device. Do you get better flavor out of higher ohm coils?
1: Would you get the same vape: No.
2: How would you choose one: just try one; start low and move up till you find the sweet spot; the sweet spot can change over time as the coil and wicking gets used
3: Do you get better flavour out of higher ohm coils:
If you use a higher ohm coil and you get better flavour, it might not because the coil is a higher ohm; the coil is probably also a different gauge wire.
You might also have a dual coil compared to a single coil.
The different coil will not so much have different flavour, but will have different power requirement; the higher powered coil will vape more faster.
wicking also contributes to flavour, so the cotton coil will taste different from the silica wick coil
