Better is subjective to the user. Some people (probably most) don’t care about a decentralized option, or crypto. If they don’t care about any of that stuff then there are much better options than Nostr.
Marketing can get Nostr over that hump, but the only Marketing I’ve seen has been focused on the very things mentioned in this comment. That won’t grab mass appeal.
If you want users then figure out what users want, and offer that to them. Otherwise users will find options that are not Nostr, and Nostr will fade into obscurity because of it.
