I also prefer the second (later) Telarc version. In theory the idea of recording the organ separately--in a different time and place--sounds awful--certainly a turn-off to purists. But pragmatically I find that when carefully done it has delivered good results in several recordings made this way (e.g., the fine Litaize/Barenboim/Chicago version on DG). I might also add that, while I like the Guillou/Mata/Dallas SO version on Dorian of the Jongen very much and recommend it, I can't recommend this version of the Saint-Saens. The fiddling with the adjustable acoustics of the Meyerson (where I regularly attend Dallas SO concerts, by the way) delivers disappointing organ-pickup results in the Saint-Saens, to my ears (but not in the Jongen, where the organ sounds grand). Incidentally, there's another fine (and fine-sounding) recording of the Jongen, by Murray on Telarc. Happy listening.
