It's true some folks lead protected lives and their ceramics have never broken while towing, but I'm not so perfect. I've converted to plastics to be sure my things remain usable after rigorous travel.
I like using plastic containers to group like products together such as laundry soap, dryer softness, etc. I also keep dry goods in plastic containers for ease of storage - products like pasta, cereal, coffee and so on.
The sink cover/chopping block is a nice dual use feature, but it's quite bulky and there's no convenient place to store it, so I use a small bamboo chopping block for a cutting surface. It's just more convenient.
