Yes, if you are rounding to the nearest hundred. No, if you are rounding to the nearest ten.
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.
The number 194 rounds to 200 when rounding to the nearest hundred. This is because the digit in the tens place is 9, which is greater than or equal to 5. When rounding to the nearest hundred, we look at the digit in the tens place to determine whether to round up or down.

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.
