Ron- It may be that no genealogy program currently on the market is really an "upgrade" from UFT, except for the 16 bit complications, but you seem to understand the tradeoffs.
As to UFT's version numbering system, it stopped with the 3.10 patch to version 3.0. Version 3.10, patched, is better than previous versions overall, but the UFT 2.8 downloadable upgrade may not be an improvement over 2.7 in its handling of certain reports (I forget what my gripe was in that area).
As to FTM, versions 10, 11, and 2005 should work properly with NT/W2K/XP. FTM 9 and below tend to have major printer problems when printing the FTM Book "feature" and perhaps some other reports as well on the XP platform to non-Postscript printers. (prints half pages).
However, all versions of FTM should print OK on "NT" platform if a 3rd party (Postscript printer based) pdf conversion utility such as Ghostscript or pdf995 is used.
FTM data storage is different from, and in the opinion of most, not up to the standards and capabilities of UFT. Additionally, there seem to be more incidents of corrupted data files in FTM's proprietary database than in UFT, particularly if photo images are embedded.
