Mechanical vs Electric Gauges?

[PETERPOOP]

I was wondering what is the difference between manual and electronic gauges. Especially for Boost/vac gauges.

I know that for an oil pressure gauge, you need to run a line from the engine bay to inside your car. I was planning on using a steel braided hose and won't have to worry about it busting. My dad did that with his mustang and it's been fine.

The question is of accuracy. I heard that electric gauges are more accurate. What are you guys opinions on this?

Wanting to know because I am going to be purchasing my gauges soon, and electric gauges are more than double the price of mechanical ones.

Sorry, I'm a newb. I searched google, but they referenced muscle cars and what not.
