Oven and microwave are the two most known devices for warming up food, or cooking it. They are pretty similar to each other but the main difference between them is that microwave saves you a lot of time. In the 21st century time is one of the most valuable resources, everything depends on time, so it is important to save as much of it as possible. There are rumors going on that eating food heated in microwave is can cause cancer. But it has long been proved that it is all just rumors, and it is completely safe to heat food in microwave. In other case you can cook actual food in oven, that you can’t do microwave. But also you are able to heat food in microwave which you can’t do in oven. In my opinion both of them are very useful and it is better to have them both than to choose one.
