Good question
@Tasty Heights. A lot of regulated mods are not as satisfying to people used to instant ramp up of power from mechs. But there are good regulated mods that have very quick power ramp up and have the added advantage of lots of safety features and a really good regulation of power that mechs don't have. You just have to try a few regulated mods to see what does the job for you.
I think vapers that have never tried a mech will be very happy with most regulated mods, but those that are used to mechs, whether tube or box mechs, will spend a lot of time finding a regulated mod that give a very good "hard hitting" experience that they enjoy.
That being said, the biggest advantage of a good regulated mod to me is consistent power from a freshly charged battery to the last vape before the battery is dead before needing a charge. I really don't like the way mechs quickly lose their punch as the battery voltage drops off and doesn't deliver a satisfying vape. With a mech I have to change batteries quite often to keep the performance level high. Generally by the time a mech reaches 3.8 or 3.9v I change the battery because the punch is gone and the vape quality diminishes.
So for me, I much prefer a quality regulated vape. But it takes a bit of research to find one that is going to deliver a very good vape experience. Many regulated mods just deliver a lackluster experience with firing delays and slow ramp up times. Try to visit some local vape shops and try a few before buying if you can, with your favorite atty. It will save you money in the long run to try before you buy.
