Just my opinion...
Although any diet is better than no diet when we are overweight, I am a strong advocate for a low-carb diet of some kind when you have PCOS. This is because many women with PCOS are also Insulin Resistant (IR), also known as Syndrome X. You can have one, without the other, but if you have PCOS and you are overweight, especially around the abdomen area, then you are probably IR. If you are IR, it means that your body doesn't break down sugars and carbs like it's supposed to. When sugars and carbs. don't get broken down within a certain time, the body automatically turns it to long-term energy storage (aka FAT.)
Some women with PCOS take a glucophage, like metformin to help their bodies handle the sugar/carbs., however studies show that a low-carb high-protein diet AND a good exercise program is TWICE as effective as being on the glucophage.
Do you crave sweets certain times of the day? Do you get a bit sleepy after a high-calorie or high-carb dinner, like pasta? If you do, you probably have some level of IR, and a low-carb diet would work better for you.
Problem is, if you have PCOS, your hormones are probably out of whack. (Mine were a mess when I was finally diagnosed.) This often leads to HBP and high cholesterol, so if you go on a high-protein diet, just be careful you're not taking in too much fat and cholesterol. I hear the SB diet is better than Atkins because SB limits your fat intake, too. And I have heard that the Mediterranean diet is great, too.
Good luck!
