i like ashigaru/samourai in general, but especially how well their tor implementation works, no orbot needed. paynym support and authentication is great, too..

bluewallet plausible deniability feature is nice. also being able to select multiple receiving addresses in one transaction, which i wasn't able to in electrum..

i'm keeping an eye on the bluewallet fork cypher box, which implements coinos in its app along with other features
