I would say either of the two except B.
B comes across as too generic, ital could be any number of alt twitter's, no info there and I wouldn't click or scroll beyond that.
I think there's a lot of generic design slop everywhere and it's really not eye catching at all. This could be an advert for a bank account or a migraine relief tablet etc etc. it's become very background.
So at least A and C actually have some info to read.
I think I general nostr people should look at something like farcaster's pages and marketing. Would you click on it, scroll more? Probably not. That is how a non-nostr user sees the nostr equivalent. Farcaster marketing also looks and reads like generic slop (slight aside: is everyone writing using ChatGPT or does it just seem like this?). People see slop and ignore it.
It's quite a difficult task actually. I would probably pick the least 'slick' slop options available as a general rule.
