Xamarin.Forms Collection View

What would be the best way to go about re-creating a view like iOS' UICollectionView in Xamarin.Forms? I need it to be cross platform. The two options i thought of right off the bat are using Xamarin.Forms.Grid, and Xamarin.Forms.Listview (Customizing the cells to have 3 "Columns"). Any other ideas or input? This is going to be used for an image gallery by the way.

Thanks
