For me the front-and-center relay visibility helps solve the "Is this thing on?" UI problem. (Someone else came up with that term, I stole it.) As you post you see the note hit the relays one by one, it's confidence boosting. Also shows errors when it doesn't hit a relay, you can check why.

Also you see up top which of your relays are online. Sometimes if nothing's happening on refresh I'll glance up, it shows 0/4 relays, I move my VPN to another location, then all 4 come online one by one. (VPN issues can mean other websites work fine but most of your Nostr relays are offline, making you always unsure of the online status.) Things like that.

And it just helps you feel the pulse of Nostr, like you start to understand intuitively what it's all about.

Plus I'll sometimes hover over the relays of other people's notes just cause I'm curious. Like your note, I'll have a look at say to myself "oh okay, using their own relay, cool".
