That's the only thing that matters, really.
The selling point of EV certificates is that (1) they are very visible in the browser and (2) users care enough about that to make a difference to your business.
I haven't seen any surveys or A/B testing results about (2) but since (1) is no longer true this is moot.
It means you should just go for the cheapest certificate, which means free nowadays.
First thing to note is that Firefox is largely irrelevant versus Chrome and Safari in terms of marketshare.
Chrome no longer displays EV certificates differently, I believe, that about 2 thirds of the market.
The second thing is (2) is my previous comment: Even if an EV certificate is displayed differently, does anyone care? Does that impact my business to make it worthwhile?
