None of the above.
We have gone through this before, as much as we hate the metric system, the standard measurement of perf. is the amount of peeks or valleys in a 20 mm or 2 cm spacing.
Use combination of three perforation gauges:
Metal (marked in mm as well as perf sizes)
Clear plastic (marked in perf sizes)
White plastic (marked in mm and perf sizes).
Same as Cal - have several dif gauges
I use the US Specialized Multigauge which is a clear plastic tool.
I also have a plastic basic Showgard gauge.
Several gauges, overlays for grilles and Irish overprints, paper samples, reference copies of forgeries, color samples (not gauges), etc. All the things most people end up with after a few decades of collecting..
I have two:
Glass Hawid 8 to 16
Plastic "Peerless" 7 to 18
Both picked up when stationed in England where I started my GB collecting.
I use the plastic Scott Multi-gage but I also have the Specialist gage that I use to measure distances.
Both of my are clear plastic. I have the Scott Multi-gauge which is what I use the most. I also have a Sonic Imagery Labs Precision US Specialty Multi-Gauge, but rarely use that one.

So do I.
But we've been changing to the system for the last 50 years and where are we?
As far as I know only cars are about 95% metric.
The number is a ratio so if one defined an English version as perforations per 0.79 inches you would get the same number. My issue in general is that catalogs are always rounding the measurements to nearest 1/4 . This works most of the time.
I work on my cars and outdoor power equipment and most everything is metric. Yes, a 1/2 inch wrench may work at times. As an mechanical engineer designing parts, I designed in metric since the well known company was international so we followed metric - drawings A0 to A5, etc. When we spec'ed metal thickness we used expanded tolerances to allow using metric materials or English material when not critical.
I use only a Gibbons Instanta.
I couldn't resist this
I use a metal gauge, it’s in metric.
I use a SAFE Perfotronic2 and a plastic gadget, all in Metric.
Same as Opa plus SG Insta..Michel Perfoscope which I found the best since it also (electronically) measures distances and angles. Never fails.
The US had a chance to convert to metric during the Carter administration and our wise lawmakers in Washington voted not to do it! Lawyers regulating technology!
It caused several mind boggling errors, costly ones such as the mirror of the Hubble telescope! They had to fit it with a corrective lens!

One of the amusing things regarding Canada going metric is that the land and road numbering system is still imperial. I live at the junction of 84 North and 95 West, this would, in metric be 134.4 North, 143 West. The road signs are still Imperial but distance and speed signs are Metric as are all over measurements.
The land was originally divided into one mile squares for settlement purposes.
This is my Gauges that I use.
The Horner-Billt was my first when I was young. I now use the White Ace top middle the most. The Linn's I use when I measure the fractions of perforations.
I use all of the above, plus the Kiusalas United States Specialist Guage for all my Washington/Franklins.

Does anyone use the Kiusalas for Canadian Stamps?
I’ve never used one, but I googled it. It looks like a good one and they have a special one for Canada.
Do you use?
A paper perf. guage on MM standard?
" " Thousands of an inch?
A metal perf. guage on MM or thousands of an inch?
A clear plastic perf. guage on MM or thousands of an inch?
A go/no go guage for any type of stamp ID?
