Which organ does this piece sound the most convincing?

Of the two sampled organs, I like the first one more, because of the registration, nice sound, but……if you listen carefully, things are missing in the sound (sampled, like a photo of the sound as it sounded at the ”moment it was made”). I explain; In Organteq I feel as I was standing in front of the organ with some pipes to the right and some to the left, and I can hear where pipes are located in space, it’s so realistic ( it is heard especially in the bass tones, 3D configuration). This is not heard clearly in the sampled ones. Then, as someone said and I agree, an actual pipe organ is so complex, that it cannot be 100% perfect: there is always a pipe slightly out of tune, there are key clics, there is the blower meowing somewhere…In Organteq, menu give you access to a panel where you can detune/fine-tune the whole organ, note per note (can’t be done with sample). This could make Flores’s example even better, if someone think the sound we hear here is too perfect to be genuine. These things and many more make, in my opinion, Organteq livelier, more realistic, more lifelike, than sample based variants (which sounded quite good here).
But, as I use to say, it is of course always about personal preference. People probably should go with what they like and enjoy. Modelled is my choice. Not bored so far

And thank you, James, for comparing these organs, and for your music - always interesting
