These days I vape almost all the time on mechanical mods with sub-ohm setups. I started with mech mods in early 2013 and I'm now very comfortable with them. My most used mod is
a Reo Grand which is a mechanical bottom feeder and there are no good regulated BF'ers around that I know of (that may be changing soon) so that is another factor for me.
If I were getting into it now I'm pretty sure I would go with high powered regulated mods. The advantages are improved safety, the power level stays the same throughout your vape as the battery discharges and the ability to dial in your vape for different build resistance and for different times of the day seems like a great feature to me. You don't need to use sub-ohm builds with the regulated mods because you can turn up the voltage with higher resistance setups and get a superb high power vape.
