the easiest one to get is a 7" 3.62 LSD - found in XR4x4 V6's and cossie 4x4's - these arn't cheap these days though 
(cossie 2wd's have 7.5" diffs with a 3.64 LSD, but these don't fit in all the chassis...)
or 7" 3.92 LSD are found in the 2.0 XR4x4's (rarer)
but then you can mix and match crown wheel and pinions to make an LSD in 3.14, 3.38, 3.62, 3.92 (& custom made ones 4.1, 4.44,.....)
or use aftermarket LSD's (quaife ATB's etc...) to turn an open one into an LSD
one thing to mention is if you want to use a ford LSD then you'll need to use bolt-on driveshafts (at least at the diff end)

do you know which type of 2.0 sierra diff you've got ?
there wasn't just one kind I'm afraid (some help here: inky
)
as far the idea diff ratio goes you'd need to factor in: gearbox ratios, wheel/tyre size, the engine power band, the type of driving your doing
and even just your preference
if the cars one the road already then you you'll know if you think its geared too high or too low over all (ie. are you gears before
you've run out of power.....)
as for the best LSD that depends on your budget as much as anything
