Jonathan,
If you look at the links that Ian sent me, the one for the tool stacks
(http://wiki.xen.org/wiki/Choice_of_Toolstacks) will show you that
XAPI (The tool stack for XCP) has the most  features. It would depend
on if you need those features.

  My next question would be regarding future proofing.  I know that
with 4.2 the xl toolstack has backwards compatability to the xend, but
in the future, will all the tool stacks be consolidated or pruned down
to just one?
