Other discussions about Bach organists (with integrals or not) can be found in this thread:

Maybe they can be merged by a moderator/administrator?

About my favourite 'integrals': I would probably pick Ewald Kooiman (Coronata, OOP), Bram Beekman (Lindenberg, OOP) and Bernard Foccroulle (Ricercare). All three play a solid, rather straightfoward (which I like), nicely registrated Bach, with articulation and phrasing (not too much legato) that I like. They also seem to be aware of the various acoustics of the various places they play in. All three have picked really wonderful (restored) historic organs. In most cases I find these historic instruments more colourful than modern (neo-baroque) ones.
Very interesting integrals are also delivered IMO by f.i. Alessio Corti, George Ritchie, Marie-Claire Alain, Hans Fagius, Wolfgang Rübsam (especially his - now OOP - first integral), Helmut Walcha, Gerhard Weinberger, Lionel Rogg, Olivier Vernet, Christopher Herrick, Ton Koopman, Wolfgang Stockmeier, Knud Vad, Werner Jacob and and and .... all the ones I forgot to mention .
I find so much to enjoy in Bach's (organ) compositions that I'm only rarely really disappointed by an interpretation.

But I do have my preferences, of course.
