I agree with you, there is no alternative to StartCom right now in wildcard certs. While GNOME got a free account to get those certs, the last time i checked is still the cheapest way to get wildcard certificates (60 usd for unlimited wildcard certs).
It also removes the complexity of having to deploy let's encrypt certificates every X months without storing the LE's account key online. But if they release certificates for anybody claiming to be you there is no advantage in this area.
