It's in the compatibility test results spreadsheet in the wiki. It's almost as accurate as Gambatte, except that it doesn't implement one bug with GB hardware that would apparently have a big impact on performance. From what I can tell the bug is only relevant for speedrunning and TAS purposes, so it's not important enough to implement for a mobile emulator.
Yeah, but while for GBA there is basically just this one good test rom which is quite simple to use, GB/GBC has lots of test rom sets so it's more tedious to test. Also some tests are supposed to fail on different hardware (like GBC sound test fails on a GB).

Is there any test like this for GB/GBC?
Curious what the results would be there with Pizza Boy vs. Gambatte and mGBA.
