I am mostly a Damus user, though occasionally I’ll get on Amethyst and test out Primal here and there.

I have not found any web clients that work well.

Nostrudel might be leading in web, I’m not sure, but even there you don’t see reactions in the feed without clicking through the note. Maybe you do, but I’m not seeing them. The lack of consistent experience across web clients makes it hard to use them.

It feels like nostr is inherently more mobile friendly for some reason.

In terms of testing, I probably tested more clients than anyone here. When I ran nostrapps I had to test them all to take screenshots.
