I'll offer my experience.

'md' is quite good for the most part.  The two drawbacks I've seen are
that solid lines (as in animation) end up rough, rather than smooth. 
The second problem is that solid vertical lines (like can often be found
with some letters in fairly small text on the screen) can become
checkered, and even show some movement.  I haven't been experiencing the
latter problem in a while now, so I assume there has been a
fix integrated in mplayer-1.x.

'lb' is better, as it doesn't have the problems listed above, but it has
some of it's own.  It needs both fields to match-up, exactly, so it is
quite prone to producing 'ghosts' either if your interlacing isn't
perfect, or if you have a telecine signal that the detelecining filter
doesn't fix 100%.

'pullup' seems to be the best of both, IMHO.   The only problem I've
had is, if you don't have a very clean video signal (something other
than a DVD) pullup will tend to still leave some interlaced video.

That's just been my experience, so don't take it as definitive.
