I'd like to create a multiple rows + multiple columns view.
I think I can either use table or grid.
Which one should I use over another and why?

Table
Table is just a layout, and could be complex for complex views. Just think in spreadsheets. You can merge columns and rows to get your layout.
Opinion
You can use the option you want, according to your needs. But if you are looking to organize your web content, use grids; If you need to deploy data use tables.
