The test equipment stable is a perfect analogy. You do not trust a workhorse like the B&K 440-445 to
gently restore any CRT, though you have the adapter or gun-switch/socket adapter to do so.
With only one meter, the 445 is a tad cumbersome to compare cutoff and emission while switching between guns. I do like the way it TESTS roundies and deltas because the scale is bigger and easier to log readings from.
I trust the 445 to test my delta gun color tubes but only the HK gets a whack at first
cleaning (using 110Vac) only THEN
rejuv-ing (using 300vDC) if cleaning fails to get some action.
While a "made-for-color" CR70 or 465 may work best restoring CRTs,
testing them is best left to a period-correct device for what your testing.
