100 mAh is roughly akin to 1 hour vape time. 600 mAh = 6 hours. 1000 mAh = 10 hours. This is a rough approximation, and is taking for granted you are using a fixed single voltage battery. As you use a battery, it starts out at around 4.1 volts and the voltage gradually drops down to 3.2 volts and will then no long produce vapor. In between that time period, the vapor starts strong and gradually decreases. An "inconsistant" vaping experience.
The Provari is a regulated mod that uses boost circuits to allow
voltage regulation. The regulator continuously monitors the battery's drop in voltage during use and adjusts the output to keep the voltage to the atomizer to what the user set. This uses additional battery energy. The boost circuits also allow for the creation of
higher voltage with PWM (pulse width modulation), which also uses additional battery energy.
The Provari is 90% efficient in its battery useage, better than most regulated mods. It's processor is also one of the most accurate on the market, keeping the voltage that you set within 1% accuracy. The majority of Chinese-made regulated mods such as the Vamo, Lava Tube, SVD, ZMac, etc use a 33.3 hz PWM (rattlesnake effect) while the Provari, DNA mods, and the iTaste MVP use a higher PWM, 800 hz in the case of the Provari.

Anyway, this is why it may seem to you that an eGo may last longer than a regulated mod. They aren't using the battery's resources as hard as a regulated mod is. However, that regulated mod is going to allow a
consistant vape from start to finish of each battery, and is going to allow the user to use
higher voltages to suit his needs for a better vape experience. A regulated mod is also going to have
superior safety features which will guard against short circuits within the device.
There will be no need to carry multiple cigalikes or eGo batteries which will literally fill up a pocket. Just one mod will suffice, and a rather smallish spare battery for that "just in case I need it". This is not the same as carrying "a pocketful of batteries".
Does the Provari provide for a better vape experience?
