At the time that Pfizer and Moderna vaccines were developed and tested, we were not aware of the variants (SA, UK, etc) and those vaccines were not tested against that. J&J has the distinction of running trials specifically with the SA variant in mind. In short, the previously released vaccines would likely not have the same efficacy if they had been in trials a few months later. So the gap isn't actually 66 to 95%.
