This is totally normal. You have to understand there is a difference in firmware. How your alien achieves said "_____watts" is where your seeing a difference. Because of the firmware. All mods get to said Watts and temp differently. Some curve, some are instantaneous, some rise slower than others.
That being said, your Charon is imo a ton better than your alien.
Wich do you prefer. Without reading too much into it let's do a test. 60 watts on each mod same tank. Wait 4 minutes and pull from one wait 4 more minutes then pull from the other one making sure your pulling for 4 to 6 second from each.
How and where does it differ?
You have to set up a controlled experience.
Sorry for lengthy answer. My brain goes into overdrive thinking about this. About all variables that go into vaping.
