In 2021, PMI introduced Authorized Training Partner (ATP), replacing the REP. As part of this significant change, PMI will be the only official PMP on-demand course provider; no ATP can provide on-demand training eligible for the 35 contact hours. PMI published the list of ATP. ATP providers can only teach the official training material provided by PMI. A PMI licensed trainer must carry out the teaching with an ATP instructor badge in live virtual (or in-class) settings. Essentially PMI has standardized the PMP training and the competency level of the ATP instructors. It should be noted that all ATPs do use the same content, and it is content that they did not develop, nor do they have the option to update or edit the training material. In fact, PMI outsourced the development of this content to a third party that was not a project management training company.  While the instructor-led training will be very similar because it is based on the same course material provided by PMI, ATP programs are packaged quite differently, and it makes sense to compare.
