People need to be very careful with this, because not only are there some PDF formats that only work with Acrobat, but I've encountered issues where the PDF opens correctly in Preview, and you can fill them just fine, but if you save it and send it, and the person opens your filled PDF in Acrobat, the text you entered will be completely jumbled.
If a PDF is meant to be printed, who cares, but if you're sending it to someone, make sure to open it in Acrobat and check if it's formatted correctly; ideally, make it in Acrobat.
