Either one works, provided that you do the math correctly.

If you are measuring voltage across a known load with a scope, then peak-to-peak works best.
If you are measuring with a peak reading voltmeter, then peak works best.
If you are measuring with an average or RMS reading voltmeter, then RMS works best.

Math is math.

What's in your wallet?
