For anyone who has tried switching over, what's your experience with them been like? Were there any hidden upsides or downsides you weren't expecting? What about coverage? It's really hard to ignore them when they keep spamming ads to YouTube, my favorite podcasts, etc.
Same. It's been great in the USA but it was entirely unusable for a full week in Europe. I had a ticket open the whole time and they could never get it to work. I demanded a refund.
