"best flavor" and "most amplified/enhanced flavor" are 2 different things really, but yeah most will say that the more flavor enhancement the better which is why the rm2 has always been so highly regarded.
on that note though I will add that personally I think there is such a thing as too much enhancement in some cases. I made a chamber reducer for my cyclone with afc and by playing around with various increments of chamber size and with some juices and with the smallest chamber size it can get to be just too much. some juices I open it up just a bit and it affects the flavor big time. also reducing the chamber I no longer need to run duals in the cyclone with afc I can get great flavor and even too much flavor with just a single coil even. chamber size is a big factor. adjustable chamber volume is very effective to dial the flavor in, surprised there aren't any atties with adjustable chamber size. adjustable airflow and chamber size really lets you dial in the vape so much, both make very dramatic changes to the vape and combined they really make for a wide range of tuning ability
Agreed, with El-Kamino, if I enhance the flavor too much (dual coils on some atties) the flavor becomes so strong to the point where it is unbearable. That is why adjustable everything is very important. YMMV.
