I see Jim beat me to it, but 75 - 80 watts doesn't mean a thing. If you built a coil that fires well below 40 watts, chances are you'll be happier with the flavor.
That's not actually accurate. Wattage + airflow are the constants, while draw time is the variable. To over simplify an example, the following would all produce equal flavor (there are more factors to consider, but we'll leave the science out of this discussion for now).
10W, mouth draw, 8 second draw
20W, mouth to lung, 4 second draw
40W, lung draw, 2 second draw
80W, lung draw, 1 second draw
Now, if that 80W vaper took a 4-second draw, he'd have the same vapor density, thus the same flavor, but have 4 times the volume of vapor (thus "cloud-chaser").
Remember we removed the science, but one major differing factor is coil heat ramp-up time. The higher the wattage, the longer the ramp-up, so those used to high wattage know to start a slow draw and increase the draw as the coil heats up. Setting that factor aside, each of those setups in the example above would produce the same amount of vapor, with the same amount of air volume, thus equal in flavor. It's the density of the vapor that makes a good flavor atty, not the wattage.
The difference between flavor and cloud chasers is that real cloud chasers (competitive) tend to really open up the airflow, including drip tips that let more air in, which only reduces the density of the vapor and thus less flavor. Otherwise, there really is no distinction unless you want to use a more accurate term like "volume chaser" since flavor is equal.
Atty's like the Kayfun and Kabuki use other tricks, such as reducing the volume of the vapor chamber, which will give you a more dense vape, thus better flavor. There's a lot more science involved in different designs, but there are some basics. If you have a dripper and want more flavor, fill in some of that empty space with something solid - metal, insulator material, etc.
There are several members in the ProVape forums that have really increased their wattage since they first started posting - nothing crazy, but maybe started off at 7W and are now at 14W. Those people have a better understanding of what I'm talking about above. The same is true for those of us who use even higher wattages.
