There’s no one single best way to make a point. The real question is which is the best way to do it in this or that situation. For instance, you might do best with speaking a bit louder on the part you want to emphasize. So compared to what’s around it, the louder part will stand out, thus providing emphasis. Then again, a gesture might be your best approach. Repeating the point to make sure everybody got it and stress it’s importance is one more technique. Using a powerful example to illustrate your point and/or its importance or effectiveness is another strategy.
It would show that you didn't just read something from one source and believed it. When researching it is good to read around and see different results or if the information may be the close to what you gathered elswhere etc.
