Not sure what's your point but I would prefer my Electron apps to run with Firefox's engine if possible since it's the browser I mainly use, it would use much less memory.
It would be slower and that's all that matter.
Ram is dynamically allocated and chrome has arguably better caching.
Ram usage has only one user facing drawback, it's when it affect negatively performance.
Chrome then outweight Firefox on your own criterion, by one indirection.
Anyway Firefox lack many features useful for "electron apps" and this new file system acesss will add to the list

I don't want to use chrome, so it's never going to be an option. The best option in a ideal world is the browser the user is using since there's not that much resource needed to open one more tab. Some APIs around that would be ideal.
