Would have been good to see Safari and Opera in the assessment too.

As it was mentioned in another comment, you either leave out Safari or Edge, since there is no OS where both are available. Obviously, in order to obtain a meaningful comparison, you need to run all your tests on same OS and same HW specs.

You could easily use the same hardware, and maybe run Chrome in both OS – giving you a shared reference point. It'd also make the comparison useful to people using OS X.

Edit: I just ran the JetStream benchmark on OS X (El Cap). Results:

- Safari 10.1: 306.25 ± 5.8662

- Chrome 56: 198.77 ± 10.059

- Firefox 49: 234.56 ± 19.496 (ran it a second time after update: 235.04 ± 6.0682)

Their results:

- Chrome: 184 ± 2

- Firefox: 154 ± 4

- Edge: 219 ± 5

Yes, this would be interesting indeed.

Well, modern Opera is very similar to Chrome, as it is Blink based. Agree about Safari.
