Interestingly... after looking at your links, I saw a third JSP set, also mastered by Ted Kendall -- of the post-war recordings:

I have some of this on very good RCA-Bluebird cds, and haven't heard the JSPs. But JSP is cheaper, another 5 discs, and also mastered by "The Man" when it comes to early Django. Again what is considered by most to be less essential than the earliest, but still some really great music, in better sound. Some of those post-war recordings have Django playing electric (which many purists derided at the time -- probably still do). Sometimes you hear influence of the bebop revolution in Django's playing. Which also, many purists derided at the time.
I don't know if there is or should be a "don't recommend recordings you haven't heard" rule. But I have heard other releases of the same material. I'll bet having Ted Kendall do the remastering makes that set at least as good as what I've heard, likely better. And that's a period that should not be left to just the Django-obsessives.
The obvious bad part of my advice is that it comes down to "Spend more money!!!" which everyone already knows.
