Brown rice has lower glycemic index and better to diet with but there is no comparison to good sushi-grade white rice cooked in a high quality rice cooker like a Zojirushi.
Skip the sh*t brown rice typically found at most grocery stores and find a local asian market which typically carries a much higher grade of brown rice that is "stickier" than the typical long grain brown rice that is more common. A good medium grain brown rice is far superior to a long grain brown rice found on supermarket shelves.
I eat a lot of rice both when bulking and dieting....I typically include it in one or two of my meals each day plus I married an Asian so I got the inside line on good rice from bad.
Buy yourself a good rice cooker too because it will pay for itself within no time and lasts forever if you buy a quality brand....nice Zojirushis start around $100 and are bulletproof and easy to use and clean.
