what the heck is the diff!!??

The advantage of a regulated mod is that you can vape at a wider range of ohms. To get the most out of a 30 or 50w reg mod, you'll want to use a higher ohm coil -- now you're probably asking "Won't that take too long to heat up?!" If you're using 24/26g coils, probably. 28g maybe. 30g should be good for getting a higher ohm coil without taking a long time to heat up.

Also, consistency, battery cutoff, safety, etc.

The reason for subohming on mech mods is to get the wattage up considering you're at the mercy of your battery

Dual 3.9 Ohm 30g coils (1.8 Ohm total) are quick to fire on a DNA 30 style mod.

I was under the assumption that the chip in the regulated mod would draw more power from the battery as the voltage drops, in order to make up for that drop (using a capacitor or something similar), which would shorten the battery life. While a mech just uses what is there.

You are correct that battery draw for the same wattage goes up as the battery dies. That may be offset by being able to go "deeper" into the battery vs a mech when the power level becomes unacceptable. If you need the extra life from the regulated mod, you can decrease wattage as the battery runs, which would be analogous to the way a mech runs.

For the OP, the answers are safety, consistency, and coil building flexibility. Possibly battery life depending on the specific setups being compared.

You know what, Tom is 100% correct if not chatting about a switching regulator lol... Even still some switching regs are horrible.
