People who need an extremely high performance JavaScript engine, where the extra performance is worth using an engine that's hard to embed, has an unstable API, and an absolutely massive unwieldy Google-style C++ code base with all the pain that entails, plus a JIT and all the limitations that entails, JITed V8 is the right choice.

People who just want to run JavaScript code where performance isn't such a big concern would prefer something like Boa (or the other engines listed on the comparison benchmark page).

Both have their uses, and their use case is almost entirely non-overlapping. You wouldn't choose Boa for a competitive web browser engine or as the runtime for your back-end server software. You would consider it for a plug-in system, or maybe a game's scripting system.

What about people who want performance somewhere in the middle? There is clearly value in knowing the performance difference.

I'm not saying that there would be no value in having benchmarks which compare the JITless, easily embeddable JS interpreters against JITed, hard-to-embed browser-quality JS engines like V8 and SpiderMonkey. I'm just saying that those engines aren't really Boa's competitors, certainly not its "main competitors"; it's a different kind of thing that serves a different need.
