With it set to off on these models, the frames are repeated to get to 120hz. And of course some are better than others,
Certainly more than there were last year, but still these are mostly high end models that do it (like Sony's XBR line), while 120 Hz is offered on many entry level sets now, even from "off-brands." And the entry level 120 Hz offerings of many of the vendors you mention do not do native 24p support with 5:5 processing.
I'm not going to sit and count up model numbers, just going by what I've seen in person at CEDIA and CES as well as vendor's line shows.
Many people assume that a set that has a 120 Hz feature automatically supports 24p content better than a set that does not have a 120Hz mode, and it's not a safe assumption to make.
Plus, as you've said, the way that different vendors actually handle 120Hz mode varies considerably. In side by side demos I've seen, the JVC 120Hz TVs with ClearMotionDrive III eliminate motion smear and handle judder extremely well (and quickly!) vs. competitive sets. But this processing is only available in JVC's top model LCD TVs.
Like anything else, 120 Hz is just a number and not a magic bullet that's going to make one set look better than another.
My two cents...
