Oil pressure gauge

I am replacing the amp meter, previous owner installed, with a voltmeter. While I am at it I am replacing the oil pressure to have both gauges look original. Found out the oil pressure gauge is a mechanical gauge. While not original looking, I was of the opinion that mechanical oil pressure gauges were more accurate and reliable. Opinions on matching gauges or leave the oil pressure gauge as is?

I did the same thing, replaced the broken original with Autometer classic 2". I used mechanical oil and a matching volt gauge. I have used mechanical oil gauges where I can, they are usually more sensitive to pressure changes than electric.

Just make sure to use a metal line with a mechanical gauge.

Mechanical gauge already installed, just wondering if it made sense to change back to electric to match voltmeter…

I considered this when I changed to a mechanical gauge. When you consider the cost of the gauges which are close to the same and then the sending unit you'll find it is as much if not more than the cost of the gauge.

Mechanical gauges are more reliable and accurate.
Aesthetics or reliability? Your answer to that will answer your original question.
