I looked into it for my own test262 project. Jint.Repl binary is usable for eshost-style testing but needs a couple of fixes and stuff pulled from Jint.Tests.Test262 - I opened a PR: sebastienros/jint#2326

98.91 spidermonkey (nightly with experimental options)
98.05 libjs
97.37 escargot (built with experimental features)
97.28 jint (4.7.0)
96.31 boa (validated against boa_tester to ±dozen tests)
94.94 graaljs (25.0.2 with experimental features)
93.19 kiesel
91.87 jsc (with experimental features)
86.00 asynkron

Using my own test harness - still ironing out bugs in it, but it looks promising to be more accurate than tc39/test262-harness.
