It depends on the rest of your text. I'd personally go with option 2, since it sounds more impersonal and straight-to-the-point, but if you already used something like the first option previously in your paper, you may want to keep the same style for consistency. Honestly I don't know if one formula is better than the other. What I can imagine is that the first option emphasize the subject. It may be good if you want to stress out the work that you or your team have done, but it might come off as a bit pretentious, imho.
