I'd go for the Mod 101 variable wattage option.
Purely because when you use a unregulated mod, your wattage is determined solely by the resistance of your coil. And this wattage will drop over time as your battery is used.
An example:
You vape at 20watts on a regulated mod.
An
Ohm's law calculator tells me I'd need a 0.88ohm coil to get 20 watts with a full battery (4.2v). However batteries don't stay full for long. So you may instead use 3.8v (a battery roughly 3/4 full) as a target to figure out what resistance you need. Entering in 3.8v and wattage of 20watts, gives you a resistance of 0.72 ohms.
So you build a coil of around 0.7ohms. With a full battery your wattage will be roughly 25watts. It will quickly go down to 22watts, stay there for a while and then when your battery gets a bit flatter, you will be vaping at 20 watts. Your battery will drop again after a while, changing your wattage to 18 watts. And finally after a bit longer it will drop once more to 3.4v. Your wattage would then be 16 watts. At that point, you'd have a weaker vape than you like - so you'd swap your battery for a full one.
With a variable wattage mod - You choose the wattage yourself, and it will stay at that wattage.
