Surprisingly (I thought anyway) WL was one of very few which support shared lists effectively. I bought Things for mac for myself and my partner at the time and was blown away when I discovered a $60 CAD To Do list app couldn't share a list. WL ended up being the best option by a long shot. These days I use Todoist which can also share lists nicely.
