The benefits are clear, its small, its cordless, it can be picked up and put back down from benchtop to benchtop to cooker with ease. The lid is very forgiving and will click back into place each time with little practice. Cleaning it is a dream. On the downside, cuts everything to only one size - fine. So great for garlic, walnuts, etc. I haven't used the whisk attachment yet, but could be helpful. I got it to chop onions, but too fine for my purposes. Overall I like it, but which chopper would do rough cut onions?
