As I see it, the main merit in a low pressure system is the reduction in the
risk of a system failure sending too much CO2 into your tank. With a low
pressure system, the pressurized components are outside the tank, whereas in
a high pressure system there are pressurized components in the tank.

How much of a risk this is to begin with is debatable. Also, because of the
variety of ways to go about constructing either type of system, I do not
think there is any way to compare "low" to "high" across the board.

I must admit that one reason I chose to build a low-pressure CO2 injection
is because I enjoy tinkering with stuff, and the extra metering valve gave
me one more thing to play with. :D
