There is no universal "better". Rounding off is a trade-off between reducing the accuracy and simplifying calculations. Also, if there are other numbers in an addition that are rounded to the nearest hundred, there is no point in rounding your number to the nearest ten.
In whole numbers, rounding to the nearest ten is better. And in decimals, rounding to the nearest hundreth is more accurate.

If you are rounding it off to the nearest tens place its 320 if its to the nearest hundred than its 300
It depends on the degree to which the number is being rounded. To the nearest Unit: 9250 Ten: 9250 Hundred: 9200 Thousand: 9000 Ten thousand: 10000 Hundred thousand (or bigger): 0
The answer will depend on the degree of rounding: to the nearest ten, hundred, thousand?
