3.4ohm is pretty normal resistance for atomizers, actually.
For atomizers, yes. But we were talking about cartomizers, which until recently were only available in one configuration, ~3.0Ω. In the case of the design that operates at 3.4, that .4 difference is more than 10% *higher*, which is counterintuitive for producing more vapor (because of the mindset that closer to 10 watts = sweet spot - although all other factors being equal-ish, it's still a good indicator). Thus the OP's question about lower resistance cartomizers. Now you can take a LR cartomizer at ~2.3Ω and compare it with a different design cartomizer at 3.4Ω, and although there's a BIG difference in resistance, performance is just about the same on a given battery. That wouldn't make sense if you are of the school of thought that 8-10 watts is what you NEED to have to produce the best vapor and flavor.
I totally agree with you - there is much more at play than simple wattage, which was the point I was trying to make to begin with. I think we've all seen atomizers that are the same brand, same resistance, etc that either over-perform or underperform in comparison to their brothers.
NOT to say targeting wattage is not a good way to go about things (as I quite happily puff on one of Drew's new 1.5Ω LR atties connected to my Xhaler at 3.7V...yummmm). I'm just saying it's not the *only* way, because as you say - other factors can and do come into the equation.
I apologize if I wasn't clear, and I hope I made more sense this time around!
