This question was recently asked on Houzz.com.
Choosing the best sink for you is what is most important. Ask yourself some questions. Do you like to hand-wash your dishes? Are you Left or right handed? Do you have a separate prep sink for washing vegetables? Do you need a separate sink for veggies? What is the largest pot or pan that you need to fit into the sink? Will it only fit into a single bowl? Would a lower center divide work for both fitting your pots & pans as well as having the separate space? What is the size of your sink cabinet ? Will a larger 50/50 (equally divided) work better than a smaller 50/50 version? If you don't have a large enough sink base for a equally divided sink, maybe one that is 40/60 (small bowl on left or right) may work better for your needs.
One thing I can say definitively is that you should purchase the sink-bottom-grid for the bowl that will hold your dishes. It will keep them off the bottom which generally means that your large pots fit a little better, they won't block water from draining and your sink, as well as your dishes, will last longer without the extra scraping on the bottom.
