I think you're exaggerating the stress and annoyance aspects. But I do agree that confronting a new user with "pick your browser" will be confusing for non-tech people. (Go ask any of your non-tech family members what they'd prefer based on the short descriptions each browser provides and you'll be lucky to get more than a blank stare)
I find such choices extremely stressful and annoying. If someone is not stressed out by it, that just means they don’t appreciate the impact it will have in terms of who has access to what data about you. (The chances of most folks ever revisiting this decision or even realizing they can are near zero.)
