What is the advantage of the natural gas generator? Is it cheaper to power rigs via natural gas generator than with regulator electric?

You can get natural gas for as low as $100 per 1000 cubic meters, it is usually 10 000 kW*hours - $0.01 per kW*hour
Modern high-power turbine generators go as far as 42% efficiency so we can expect something around $0.03 per kW*hour
Not bad at all. But you should seriously consider how long it will take to ROI. If you have some need for secondary heat output (say hot-water for sale) it helps a lot in terms of ROI. Unfornutaly at the moment we got $300 for natural gas locally and $0.05 for electricity so I have no chance to proof my studies for-real :-(.

In our case the primary reason is that we have free heat for our house from the natural gas well in the woods behind us. We need to determine if it would be possible to run both the furnace in the house and the generator for mining power at the same time or not.... also we need to get a quote for installation costs. Before all of that though, we have some repairs needed for our septic system, and if that ends up being a completely new septic we won't be able to do that and the natural gas generator in the same year.
