Generally speaking...lower resistance.
Lower Ohm coils Will:
Lower Ohm coils Will:
- Heat The Coil Faster and Hotter
- Produce More Vapor
- Drain The Battery Faster
- Use E-juice Faster
- Produce A Warmer Tasting vape
- Heat The Coil Slower
- Produce “Less” Vapor
- Provide A “Cooler” Tasting Vape
- Use Less E-Juice
- Prolong Battery Life

It's a kind of compromise between lower resistance (faster) and more wire (slower)...
A thick gauge quad coil will have very low resistance, but its a lot of wire to heat up.
This is why I, personally, end up "medium" - I like instant heat. It also depends a little on your device - if you have a mod with some kind of "boost" function. And it's different of course between using a mech (fixed at battery voltage) than if you can throw 100 watts at the coil...

Most lower ohm coils use thicker wire which heats up more slowly. Of course if you put 100 watts to that coil, that's another story.
Earlier style coils like the evod/protank, use 30-32g wire which heats in a heartbeat...but don't even try to put double digit watts to those.
So it's more a matter of gauge of wire and watts than it is ohms.

generally, if you pump the same power into a thinner wire as compared to a thicker wire, the thinner wire will heat up to glowing faster than the thicker ( both wires have been configured to the same ohms...)
Resistance can be looked at when comparing your wire as a straw. The thicker the wire the wider the straw there for the lower resistance... The more bends and loops you put into that wire the more resistance your adding to that wire. So this is why you can't exactly look at resistance as a good factor... Your speed at which your wire will heat up is determined by the power you direct through it vs the mass of the coil.
Wrong
That's basic electrical knowledge and ignores our special variety of constants and variables.
In basic teaching there's an assumption that mass and current are constants. Even materials.
This makes it a basic principle.
In our case
Take 2 coils made of kanthal appropriately built for use @ 4.2V.
One is 0.2 ohm.
One is 3.0 ohms.
Both single coil.
The 0.2 ohm coil is going to be 22 gauge and a VERY significantly larger mass.
You'll be able to fire and hold the button down before it's time to raise that atty to your mouth.
The 3 ohms build is going to be 32 or 34 gauge and will fire so fast you'll want to be inhaling before you fire it.
Of course this can be offset with a 2 or 3 series battery bucking regulator, more wraps, more voltage and thick guage.
But then apply a thinner gauge at the same voltage and we're back to square one.

the smaller the coil the faster it heats up; heat capacity.
It's more about the mass of wire than the ohms.
Yet add 3 more identical coils to make a quad coil 1/4 the resistance.
What happens is you quadruple the drain on the battery, increase voltage sag...
And the lower resistance build still heats up slower.

2 ways to make lower resistance heat faster.
1 Apply more power.
2 remove wraps from a higher resistance coil. (Use less mass)
That's about it.

This pretty much sums up how I feel every time I open one of these threads and read the replies:

The problem with any comparisons is making "all else equal". If, for example, you wind the exact coil except out of Nichrome rather than Kanthal, it will be lower ohm, draw more power at the same voltage, and therefore heat quicker. However, it will be identical when driven by a VW mod at the same power setting.
In real life with same airflow and voltage, a a coil the same except for thicker wire will heat faster due to being higher power compared to the airflow.
With same power and airflow per surface area, thicker wire will heat slower. Thicker wire has more surface area per length so to keep the surface area the same, it can be shorter proportionate to the diameter increase. However, the cross sectional area increases at the square of diameter, so even with the shorter length it weighs more. However, typically when different wire or resistances are compared there are usually other differences that swamp this effect.

With no air flow...
Or with appropriate air flow...
IME, this theory falls apart swiftly.

^^-- you're right in that I'm talking about how hot the vape is, not how fast it's getting there,regarding airflow (mostly). As that paragraph goes, it would heat up at the same speed at least until hot, but draw a lot more power if voltage is actually maintained... Plus the OP's question "glows" infers dry burning, not a vaping situation.
Resistance is only part of the equation if you use mechanical/unregulated mods. Even then, it's all dependent on how much wire you are trying to heat up and how much power you use to do so. You can have a huge chunk of low resistance coil that takes longer to heat up than a smaller coil of a higher resistance. It's mainly about finding a balance between power and mass. To me, aiming for a certain result makes more sense than aiming for a specific resistance.
With regulated mods, the mod decides the power output - not your coil resistance. As such, your coil resistance don't play a part in how how slow of fast it heats up - only how much power you use to heat a certain amount of coiling material.

Have we learned nothing from our pwofwssionaw vapor friend, Victor?
Even with regulated to compensate with higher power, if we install a build that's too high in resistance for our settings (Read; too little mass for the power applied) things get real hot, real fast.
Exibit A...

Indeed. Vaping on "pwofwssionaw" power levels is sort of like tractor pulling; using huge chunks of metal as a means of spending a whole lot of power on not going very fast.
Like you, I blame mass - not resistance. I don't have a heart to blame Victor, tho. He's great.
