Are you sure Edge is better? Doesn't Edge add a lot of its own unique, er, "contributions" to the browser experience, so to speak? Why not Firefox or Ungoogled Chromium or something else like those?
I don't think it's that much better, but I felt like if I tried suggesting Firefox she would be very hesitant. I just wanted to avoid her to mindlessly be sucked into Chrome.
If that's all that nags you, you're either lucky or unaware of the other stuff. For me there are at least the "Save time and money with Shopping in Microsoft Edge" data collection stuff, the "Get notified when creators you follow post new content", the "Show suggestions to follow creators in Microsoft Edge", the annoying sidebar, etc.
Probably a combination. I get an annoying song and dance the first time I open Edge after an update, but I don't use Edge on the regular. Sometimes if I'm trying to buy something Edge will tell me that a site has coupons, but I don't get interruptions that often.
I mean if your problem with Chrome is data collection, then interruptions are kind of beside the point right? You should be looking into what data Edge collects, including the shopping stuff I mentioned. I'd go check out all the settings pages if I were you, and make sure these options are off (and any others I neglected to list). OTOH if you're just using Edge over Chrome due to other reasons then I guess none of this is relevant.
