Sorry for taking so long to come back to you - it's the difference in Time Zones.
The current trend tends to be towards coil builds with very low resistence - well under 1 ohm used with a lot of power 20, 30, 40 watts and above and featuring juices with a low nicotine strength.
These type of builds produce a lot of vapour. use a lot of juice but to my mind the court is out with regard to the flavour they offer.
I was given the atomiser in the first picture by a friend some time ago. It's drip tip is as wide as a cannon mouth and it is a big beast - so logically you would not expect it to be a flavour monster ... but it is, because I built it a simple single coil using 28 Kanthal at 1.2 ohms, set it at 3.7 volts/11.4 watts and use it with a home brew fruit/menthol juice at 16 strength.
I've never needed to chain vape it. Personally I also think flavour is partially governed by how an atomiser is vaped. For me I take it slowly, maybe drawing in for about 4 seconds, holding the vape in my mouth and lungs for another four and then letting the vape out slowly concentrating on savouring each puff.
Pix are attached - hope it helps and good luck on your Vaping Journey.
