| David,
Sold a '99 SPS earlier this year for a '02 998S, so I guess I'm closest so far to your dilema...
Buy the SPS if your trips are reasonably short and not around town, if you enjoy trackdays but not commuting, if you want to tinker and tweak to exract the ultimate from your machine.
Buy the 998 if you do the odd tour on your bike, commuted, potter around rather than go nuts out at all opportunities and want a bike that doesn't require constant attention to keep it sweet.
The SPS is a full on race bike for the road - the 998 will do everything the SPS does on road/track to within a gnats, but will be more day-to-day friendly...
