Not really. Yes turning up the Wattage may enhance the flavor of some of your juices, but most juices will taste better in an RDA. Although flavor is very subjective, I believe most vapors have come to the general consensus that RDA's are more flavorful than tanks (granted there can be exceptions). I believe this is mostly due to the fact of coil building possibilities. Most tanks come with pre-built coils, most of which are pretty basic in design (single spaced coils/parallel coils), and the tanks that come with re-buildable sections (RBA/RDTA) are usually too small to build effective coils or require very small gauge wires. As a result, most tanks just can't house coils big enough like an RDA can, as most coils designed specifically for flavor are of the larger variety. That being said, there's numerous things that affect flavor (wicking/airflow/coils/temp) that could be leading to the noticeable difference in your vape.
