I couldn't recommend just one.
(Apologies for that.

)
A lot depends on the availability of the various sets, too.
But some OOP sets may be downloadable or streamable somewhere (to be honest though, I have no idea).
My personal favourites are Bram Beekman on Lindenberg (OOP) and Ewald Kooiman on Coronata (OOP).
If still available, then I would also recommend my 'fun' sets Bernard Foccroulle (Ricercar) and Olivier Vernet (Ligia).
Beekman, Kooiman and Foccroulle play historic instruments, mostly of the North German/Dutch type.
Vernets plays a mixture of modern and historic instruments. Most of the modern instruments are built in a baroque-influenced way though. Generally: very nice!
A very interesting set is a rather expensive integral, played by Ewalk Kooiman and former pupils (mentioned above) on historic instruments of the Silbermann family, built in North-East France.
The label is Aeolus. The sound quality is really superb, but the set may be OOP, too.
Besides that, organists like Marie-Claire Alain and Lionel Rogg are trustworthy solid choices, no matter what kind of instruments they play.
The 'good ole' Silbermann set with various interest (mentioned above) is interesting, too. The same goes for the Profil/Hänssler set with various organists (f.i. Kay Johannesen, Andrea Marcon, Wolfgang Zerer, Bine Katrine Bryndorf).
Personally, I prefer (restored) historical instruments, but the amount of solid to great sets is rather impressive.
Younger organists are still wild about Bach, so I may have missed one or two more recent sets. But, if you like this part of Bach's oeuvre, the listening experiences are mostly very worthwhile. All those instruments and organists have their own individual characteristics and style. It's a fun travel!
