Chrome is amazing. Having most people switching away is a hard sell. I honestly think Brave has a more compelling selling point here, even if privacy is not something that sells as well as it should, meaning its adoption will be limited to early adopters / privacy-aware individuals only.
I agree with the other comments, it's our duty to ensure other browsers still exist, we can't let Chrome have it all, but we need more than obscure features to turn it around.
On the other hand, explaining Firefox seems easy. People around me seem receptive to both privacy and closed garden concerns. I explain to them how their data is used if they do not take precautionary measures to prevent it. I also tell them that the web they know and love will get increasingly suffocated and rot away under the pressure of Google which has no concern for them or their needs. I tell them about Google's recent efforts to prevent ad-blockers from working well. I also mention other malicious tactics, such as AMP and the effort to hide the URL.
I then set up uBlock Origin (making a point it's the best ad-blocker but will stop working on Chrome shortly), Facebook Container and Multi-account Containers for a few of the most obnoxious websites. Multi-account Containers has a setting to make the association of a particular domain with a container permanent[+]. I give them a short introduction to containers and teach them to recognize when a website is open in a particular container (there's an indicator in the URL bar).
This works in my experience. It sticks. They continue using Firefox and at times even spread the idea to their social circle. It helps that in recent times concerns about Google, Chrome and computer surveillance are talked about in their regular news channels, so that I am not the only source where they hear about this.
> They care about... a smooth experience, I guess?
Ask them again. Try to understand their preference well enough that you can explain it clearly.
I am quite confident that they don't actually care about anything Chrome has to offer at all[@]. They're simply used to the colourful circle icon because they are being bombarded by it everywhere. It's the same as with IE before, only this time around it's a colourful circle instead of a blue 'e'.
> Chrome is amazing. Having most people switching away is a hard sell.
Firefox is amazing (in a technical sense) too. It's just as smooth as Chrome for me and sometimes even smoother since I'm a heavy tab user. I dislike some of Mozilla's decisions as well, but this takes a backseat to the more pressing issue of vendor lock-in given that there is no mainstream alternative.
[+] This could use a bit of UI work. After you assign a website to a container, you have to open the website in another container so that it asks you whether you always want to open that website in that container (it's a checkbox).
[@] As a disclaimer, I'm just extrapolating from my experience. Perhaps your parents are an exception and they do have a strong preference for a Chrome-only feature. If so, this is a useful thing to learn.
I checked my Firefox window and realized that they have a Shield-like feature too. Oops.
To me, Firefox's main features are the underlying foundation, and the fact they are the main Chrome contender — the rest are nuances addressed to power-users. Containers. Frankly, it's too complex for a regular user [0] who, as you say, just click on what they have been used to clicking onto.
I'm having a hard time justifying my point further about Brave than by contradicting myself around the fact privacy alone is a weak selling point... Brave is all in on privacy, they have a really clear message about it, and regular users will understand better from their website that the browser natively blocks ads [1] and more importantly why e.g.:
> As a user, access to your web activity and data is sold to the highest bidder. Internet giants grow rich, while publishers go out of business. And the entire system is rife with ad fraud.
Comparatively, Firefox's homepage lacks details. The features are listed, but why are they useful to me... not sure. e.g.:
> Automatic privacy is here. Download Firefox to block over 2000 trackers.
> Firefox shows you how many data-collecting trackers are blocked with Enhanced Tracking Protection.
I understand both statements, but someone external to tech/ad tech will probably not see that as worth unless an expert explains why they should use that browser, exactly as you explained.

Yes, but it's at least possible to configure it for them so that it will be out of their way but still work as intended. What remains is to package these presets into installable add-ons, which is already happening to some extent in the form of "S container" add-ons where S is a popular web service. For instance, Facebook Container (https://addons.mozilla.org/en-US/firefox/addon/facebook-cont...) from Mozilla.
I think it would be even better if there was a generic add-on in style of uBlock Origin which allowed downloading such container presets from some kind of repository.

On your other point, I agree that the message on Brave's website is more effective, in the sense of being more visceral and producing stronger emotions.
