UE4 or Unity for basic social VR exploration

Never worked on mobile last three years focused on desktop only VR apps. Also abandoned both Unity and Unreal at that time.

Now wanted to prototype a social exploration app for Quest, with just some geolocalized locations to be explored together with the possibility to interact by voice, and free locomotion.

No score, no complex rooms, just VR exploration with some features and locations to be added later.

Wanted to ask what engine might be more suitable for the goal, considering will be at the beginning just a prototype to be made with less possible usage of coding, easier possible development and deployment, good looking results, stable and integrated environment, future remote manegability, possibly to public test a beta without many troubles.
