The first oil pressure gauge is mechanical (even though it says electric.) You have to run the oil line right up to the gauge.. not practical for inside the car installs. The second one is the electric version which uses a sender.
The boost gauges, the first one measures boost and vacuum.. while the second one measures only boost, and not vacuum.

Yea.. some people say it's nice to have the vacuum reading too to make sure something about the manifold pressure blah blah blah.. imho it's just to look cool
