Which is better mechanical or electrical oil pressure gauge?

One changes with body ground problems, and the other one pees on your foot at a stoplight!
Probably the most accurate answer we will see!
Fact is, there’s no way to prove either is calibrated correctly. Aside from the above comments, electric is easier to run back to the dash
And all of mine are mechanical
If it's peeing on your foot, you have oil pressure...mechanical ftw!!! 
For 78 I have the electrical oil pressure gauge. If I can get the mechanical gauge and cluster would it be a bolt in? Would it be worth the effort to go from electrical to mechanical?
I don't remember if they changed from an amp gauge to a volt meter the same year that they went with an electric oil pressure?
My 1977 K-10 came with a mechanical oil gauge and a voltage gauge - the truck was a very late build date of 08/77.
Can’t recall when the AMP/Volt switch over was ?
My 78 built in late 1977 has an electrical oil pressure gauge.
That sounds right - from what I’ve seen over the years 77 model run was the last of the mechanical oil gauge setup.
Yep. I think 75 was the last year for the amp gauge.
had both mech and electric with problems .
its all in the quality of the guages and the products used in them getting there signal .
mech only use copper line . had nylon brake and dump hot oil on a buddys boot going down the road .
have had electric senders start leaking that were old . . aged out .
had a cheep set of guages in a friends can show 40psi oil all the time ....... mechanical and frozen . found out when motor was ticking from 16 lifters clattering .

Personally, I wouldn't want fluids in the cabin, if it could be avoided. Esp, in the case of bad things happening.
Agreed, this is why I think electric is far more superior.
I don't like the plastic/nylon lines but have no problem with the steel or copper lines for oil pressure.
In factory applications, they seem to not have issues. Most mechanical gauge leaks are either crappy plastic as mentioned, or poor installation
