EXS 24 Logic Sampler Users Group

Hi:
 
I'm a Gigastudio 96 owner (v 2.5), and have often wondered if I 
should jump to Emagic's EXS24 for LAWP.  I'm running LAWP 5.5, and 
had to completely uninstall Gigs and reinstall it last night as 
something got corrupted.
 
So, I'm looking for something that plays nicer, maybe, with Logic.  
For some reason, I can't demo the EXS24 MkII as it says the demo 
has timed out on my XKey.  I don't remember ever activating the 
EXS24 demo, but maybe I did and never used it last year some time.

Does the EXS24 MkII play nicely with XP-Pro?  Does it come with a 
sample library?  

How does Hallion stack up against the EXS24 and Gigastudio?  Is 
there a crossgrade to EXS?  Sorry if these questions have been 
addressed before, I tried searching the group, and couldn't find a 
satisfactory answer.

Thanks in advance for any help,
