I prefer the regulated vape over the unregulated. There's no guess work with a regulated device. You have complete control over the vape and aren't at the mercy of your battery. Also if you go with a high power mod that's 100 or more watts it really opens more building options to you. Right now I have a 24 ga 9 wrap dual coil set up on a doge. It takes forever to ramp up at 4.2v, but I ramp it up to 75 watts or 5.8v and it chucks clouds and flavor. High powered regulated devices really uncap your coils potential. The build that I have right now would suck with a mech, but getting that much power over that kind of surface area provides an awesome vape. I was considering getting a mech mod, but it really limits you to your battery. I'm not referring to amp output just to be clear. You still have to use high output batteries. I'm referring to the gauge wire you can use and number of wraps attainable while not increasing ramp up times. At 75 watts this build is an instant hit and I can easily vape it at 100 watts. But at 100 watts I cringe at the juice consumption.
