I searched and found a few threads but there was no conclusive post to answer me really. What is the difference between a 3.0 ohm single coil carto and a 1.5 ohm dual coil? Resistance? I'm wondering if buying a dual coil would be better or not, is it a matter of opinion or is there a substantial difference?

What device will you be using it on? This will help to get you to the right part.
The major difference is that two 3 ohm coils (for a 1.5 ohm dual coil) will give you twice the vapor of a single 3-ohm coil.
If...and it's a big if...your device can handle the power drain. You're drawing twice the wattage, so some smaller devices will experience a sag in the voltage. You aren't getting twice the vapor, you may not even get the same amount you'd get from a 3-ohm.
I can't say I was terribly impressed by the dual coil I tried, but that might have just been me.

The Inferno is designed to use the 1.5ohm duel coil. Once you get your Provari you can use the 3ohm carto's. Till then stick with the 1.5 duel coils.
The Provari definitely will be able to deal with it, the Inferno also looks good (it seems to be an eGo-type device of at least 650 mAh).
I'd treat it as a 1.5 ohm coil in terms of power usage, not as a "dual 3 ohm" (the two statements are identical, but it consumes power like a single 1.5 ohm coil would). Pushing to 4.8 volts, for example, isn't in the slightest unreasonable for a 3 ohm coil, but will consume 15+ watts on the dual coil.
That's a lot of power. Your battery would have to be up to that.
So what I'm taking from this is a single coil 3.0 would take up more power at a higher voltage?
Given a 3 ohm coil, as you raise the voltage the wattage will increase (faster than you'd think).
W = V^2 / R, or Wattage = Voltage-squared divided by Resistance. At 3 volts, a 3 ohm coil will use 3 watts. At 4 volts, the same coil uses 5.33 watts. At six volts, 12 watts.
Lots of people vape in the 10+ watt range, usually on a RBA. I personally prefer things around 6 watts, but that's just me. I'm happiest with a 2.4 ohm coil around 3.7 volts.
