Well HHVM is quickly losing ground to PHP v7 in terms of speed. I'm not sure which is "fastest" any more, but IIRC it's close enough that if you want to switch for the "speed boost" I'd argue it's not worth it.
In terms of Hack as a language, it's very similar to the JavaScript->TypeScript relationship. It's still mostly PHP, but it doesn't quite get the new PHP features as quickly, and there is the chance that there could be incompatibilities in the future which could cause new PHP code to start looking and acting differently than Hack code.
