Spark or GAIM/Kopete?

This may be a really simple question but I just got Wildfire installed and working and can connect via Spark on Linux. I’‘m deploying a bunch of machines inside our own network and am wondering is there an advantage to installing Spark on each of these machines when GAIM/Kopete is already there. The gui looks pretty good, is simple (for us that’‘s great) but involves adding software that already exists and figuring out how to get it to start each time a user logs in which probably isn’'t hard but is almost automatic with GAIM/Kopete.

So why would Spark be better than the already provided solutions?

Thanks in advance.
