Well, the title says it all. Sorry this is a redundant question, but the search on these forums isn't good enough to turn up where this has been asked before.

What is the best/cleanest way to restore the original 24 frames by inverse telecine?
I've heard good things about VirtualDub(Mod's) internal alorithm, but I had so-so luck with it when I tried it before.
Every guide online suggest different methods and everyone has a different opinion what's best.

I know a perfect method is impossible because some original frames only exist as fields split between different frames.

I've seen some wonderful work done on Star Wars restorations, so I know there are people doing this right.

Edit: I saw that ADM recommends:
Telecide(order=1,guide=1).Decimate()
How effective is this?
