Is a 97.6% result from VendorInvestigate comparable to 96.8% from PeptideMeter?

The case in front of me: 97.6% · VendorInvestigate · 96.8% · PeptideMeter.

These are treated as interchangeable and I do not think they are.

If both are acceptable I would like to know that, so I can stop thinking about it.

What is the actual trade-off, and does it matter at the scale I am working at?
