Neither: The better version is that which you can afford and take regularly. Once daily versions are typically more expensive but if you can't afford it, why worry? Twice daily are more troublesome but more affordable. If cost isn't an issue, get the once daily. Both will help control your sugars. Better yet, pay closer attention to your eating habits. And exercise regularly.

Neither: The most effective dose of metformin is 1000 mg twice a day with meals.
