It depends what you're picking up, but yeah, I've been using chopsticks since I could feed myself and you can't get as much stuff as you can with forks.

With rice, I can usually scoop up more than I can with forks. With noodles, I can do more with forks.

And wooden chopsticks are sooo much better than metal ones.

Also, if you eat sushi with your fingers, you should be ashamed of yourself.
