From my perspective, the vertical slice makes more sense:
- YANG subscriptions has more industry activity, and early implementations needing interoperability guidance
- YANG-Push defines a notification which places the subscription-id within the notification message (something you don't get right away with subscribed-notifications).  This makes is more useful.
- the instance examples in the transport drafts also include examples of yang-push subscriptions (i.e., the horizontal slice also has vertical elements).
- restconf-notif's HTTP2 configured subscriptions are less complex if they use only the new notification message format
