A personal room can have only one Host.
Only this Host can manage and edit their rooms, as well as launch meetings from them.
Having a personal room is the best option if you want to have full control of your rooms and sole authority over initiating meetings in them.
A team room can have multiple Hosts who all have equal control over editing and managing the room.
If you want a room in which multiple people have the authority to initiate meetings, then a team room is the best option.
