- Rabbeinu Vidal De Tolouse wrote the classic commentary on the Rambam known as Maggid Mishneh.
- The Kenesset HaGedolah writes that wherever the Maggid Mishneh says he couldn't find a proof for the Rambam, he doesn't agree.  Some even say if he doesn't provide a proof, even without articulating that lack of finding, it's an indication of disagreement.
- A contemporary of the Rivash, the Maggid Mishneh's allegiance to the Rashba is indicative through his thorough familiarity with the Rashba's opinions. Therefore, when in doubt as to how to understand the Rashba's opinion, the Maggid Mishneh's understanding is a valuable and acceptable window to determining what the Rashba means. Some say the opposite is therefore a valuable tool of understanding the Maggid Mishneh, as well.
- His tremendous dedication to elucidating the Rambam gives the Maggid Mishneh credence in deciding what the true explanation is when the Rambam's position is debatable, according to the Radbaz.
- The Rivash posits that when the Maggid Mishneh refers to the Rambam as "HaMechaber" and not "Rabbenu," it indicates lack of satisfaction with the Rambam's position on his part, but the Chidah argues that the verbiage is arbitrary.
- The first three Perakim of Maggid Mishneh on Hilchot Gerushin (until Halacha 9) were not extant even in the times of the Maggid Mishneh himself; what we have printed was probably written by a student, not the Maggid Mishneh himself.
- He and teh Ran refer to each other as "Yesh Mi SheKatav."
- Maggid Mishneh doesn't usually refer to Perush HaMishnayot.
