Of the ones you mention, I bought the remastered Grimes, Wright and Lowe. The Grimes, to these ears, sounds great with Grimes up front and sounding very prominent. I bought the Lowe because of the extra material, so I disregarded earlier editions for that reason alone. Again, sound is very good to these ears and its interesting to hear William Parker early in his career. I also found the Wright sounding really good, but my only gripe is that they didn't reissue this material with the original artwork. The album cover for 'Your Prayer' is absolutely badazz.
Overall, I've been pretty pleased with the new reissue program, I just really don't like it when they don't reissue the original cover art, as they redesigned the Murray, Burton, Wright and Ayler's Spirits Rejoice for instance. The original ESP artwork is some of the coolest around and shouldn't be messed with, IMO.
