My experience is that most devices have poor flavor. I think it's that you have to find different juices and develop better technique, in other words put in effort, to get good flavor from different atomizers. The high watt guys rave about the amazing flavor but I've never experienced any evidence it could be superior, so haven't really tried, plus I don't think I can handle anything that big or high VG for that matter.
I maintain a low power pocket vape, although don't use it a lot. When I was using a Nautilus I found it only really created great flavor on the smallest 2 airholes. That milkshake through a straw airflow seems essential to getting magic out of small amounts of high flavor juice. I get magic out of my main RDA setup too, which is still only ~15W but loose draw, but with low flavored DIY juice where the flavor is complementary to the taste of PG and VG. The old juices barely give a hint of what makes them so great in tight airflow devices.
As I lost the Nautilus, I'm back using an EVOD with rebuilt coil and cotton for the pocket. Barely over 5 watts. I'm back to using Goodejuice NETs and seem like they always were, although I've only been doing this about 5 years.
