A deeper and bigger sink with a straight bottom allows to soak larger pots and pans and stack cups and glasses, but you need a little bit more space for it, while a smaller sink fits smaller spaces better.
One of our favorites is an offset drain. An offset drain lets the water flow out even if you are soaking a large pot, as it won’t block the drain. Another great pro of an offset drain is that it creates a lot more storage space below the sink.
If you decide to opt for two bowls consider a divider that is lower than the counter. It is a good overflow protection.
