I have found many juices change with heat. In my milkshakes (DIY) the fruit flavors come out more at lower watts and the vanillas come out more at higher watts. When I vaped various tobacco menthols, I found the menthols came out more at higher watts and the bacco more at lower watts (nice blend in the middle).
In my experiments, tobaccos and PG seemed to hold up better to higher heats (VG seems to have a lower burning threshold). I also find fruits don't like the higher heat levels quite as much. But, I know plenty of vapers who enjoy fruit vapes at higher watts. As will ALL in vaping, it is ALL subjective to personal taste and preference.
I just encourage everyone to experiment. Of course that is a bit easier with Darwin (thumbwheel) than kick but in top-loading devices, adjusting kick is easy too (can just leave kick in device, remove top-cap and adjust). I tend to dedicate devices to juices and will have a few kicks - each set to a juice. But, more often than not, I vape the 8.5 watts (2.8Ω cartos and 3Ω attys) range fairly consistently.
