What’s the difference?
Technical answer:
Switching regulator - In a switching regulator transistors are turned completely ON or OFF like a switch. When they are on lots of current can flow but there is almost no voltage across the transistor therefore the transistor dissipates very little power. When the transistor is off there is usually a voltage across the transistor but there is no current so again there is very little power. Energy is usually stored and filtered through inductors and capacitors and regulation is controlled by varying the percentage of time on vs. off (duty cycle). The advantage to this is that there is very little heat or wasted power making this design capable of being very efficient.
Linear regulator - In a linear regulator the transistor is turned partly on so as to provide the proper resistance to the load so that the load always sees the same voltage. Since it is partly on there is a definite voltage drop across the regulating transistor and there is as much current simultaneously as the load is demanding. Therefore power is being dissipated across the transistor which turns into heat. This heat is wasted power and the reason that switching supplies are so much more efficient.
Simple answer:
Switching regulator:
More efficient (75-95% efficiency)
More time between recharges
Runs much cooler
More expensive
Linear regulator:
Less efficient (20-60% efficiency)
Less time between recharges
Runs much hotter
Less expensive
I offer the Linear regulated mod as an inexpensive option for people on a tight budget or those just wanting an inexpensive back-up VV mod, due to the heat generated by linear chips I do not recommend this for heavy daily use as the linear chips thermal protection can kick on with heavy use.

I also take requests for custom mods, though I cannot guarantee that want you want will be possible or within my abilities.
