I have owned the AT W5000, W2002, W11JPN, and W10VTG. Briefly I can say that the W5000 has by far the best details and imaging of any of them; it's not even close. Where the W5000 lacks is I find it overly bright and thin sounding. I Fitz F5005 modded mine and I much prefer them that way. They get a little dark and loose some of the imaging qualities, but the sound is more balanced I find. The W2002 has slightly more bass than the stock W5000 and a more balanced sound. I also has a wonderful midrange, esp with female vocals but I found it a bit colored. Compared to the W5000 it doesn't have quite as much detail and the fact it lacked bass compared to the F5005 and the coloration led me to end up selling it. The W11JPN is a very warm, suductive sound phone. It has a much more closed soundstage and darker sound than any of the other AT woodies I've heard. It is very unique. I keep it for that quality. The W10VTG has been described as a lesser version of the W11JPN, but I find them quite different. The W10VTG is much brighter with much more PRAT. However they can be somewhat sibilant in the highs. That said they sound great unamped so I keep them for that.
