This might just be me but I feel like "Kills" is way more widespread and way more well known than "Frags".
And for the sake of accessibility and making it easier for everyone to understand, I propose that we change "Frags" to "Kills"

I'm not in favor of either option (yet). But a pro frag argument is all the other cube based games use that term. So, for historical reasons, we might keep the term and maybe document it better. I feel there should be a "lingo" page in our docs anyway.

It depends on how and where you use it! And in general, it's all up to the individual. They have different characteristics.
