It probably depends. I had a great dual coil on an RDA with 32g wrapped I think 8 times which made about a 1.8 if I remember and the hits on my VAMO 5 with stacked 18350's was stellar. Right now, I'm vaping dual 28g at .70 ohms and I think I like the higher ohm as it's cooler and I think I get a better flavor. I was vaping some ahlusion juice tonight and the flavor seemed a little lost... almost like it's burning too hot. I'm still searching for my ultimate build. Only been at it about 2 months.
I have tried different coils, different wicks, different atties...
the bottom line on all of it is each of us likes different set ups, and you just keep making them until you hit your sweet spot. There is no right or wrong, just what gives you the best vape for YOU

I only do micro coils when in dual coil mode. Way easier to make duplicate coils that way. Otherwise, I can make a regular old fatty coil that will dance with any micro.
we all tend to focus on the ohms of our coils, which, of course is important. ohm's law is an easy study.
comparing, say, a loosely wrapped one ohm coil to a tightly wrapped one ohm, leads us into thermodynamics and other cool chit, most of which few of us have only a prayer of understanding, or articulating.
that's my long-winded way of saying it all comes down to personal preference, after you dial in your preferred ohms.
These are the first published photos of the first micro coil.
As we got better at wrapping the wraps got closer and eventually the concept evolved to where we got most of em to touch each other.
My take on it is that the micro inner diameter with wraps touching each other or as close as possible has always provided the best vape and cleanest coil after a good period of use vs the old school large bore 4 spaced out builds like this:
I also find them less finicky to build and consistently duplicate. Gone are the days of hot spots and uneven heating.
A micro also allows more adjustability / fine tuning the vape because the smaller mass can be positioned close to the air source (less TH) or close to the posts for more TH, higher than the air source (more TH) or low where the air flow is over the top of the coil mass for less TH. Or anywhere in between.
Somehow it got completely misconstrued by the YouTube video celebs. They pushed touching wraps and never grasped (or evangelized) the part about inner diameter.
Most people who heard about it outside of the two original micro coil threads on here (especially on YouTube and Reddit) believe a micro coil is a coil with any size ID you care to wrap as long as the wraps are touching.
Pity the fools

I personally prefer the microcoils, for me I love the knowing what I am going to get at the end of the build and can reproduce results over and over, I could never do that with the big wraps. The micros fit so much better in the smaller decked RDA's like the Igo and the Era's. I also think the produce a superior vape over all.
I agree with SuperX on the concept being lost for alot, I personally have watched vids of folks building these big fat coils and trying to call them micro but the are using 2.5-3mm silica in them, but because the coils touch they are somehow a micro.....
What works for me is wider ribbon on silica. I find the flatter heating surface creates an explosion of vapor.
