EZ bone;
Brother, in your original post, you compared the differences. I just want to elaborate and add that the 16V engines of the 2.5 and 3.0L in the 944/968 S, S2 and 968 generates up to 27% more power than their 8v Counterparts in the same displacement (16V 328cfm per port vs 8V turbo 257cfm on a flow bench)Wow!

Proven Fact. The original 924/944 GTP proved it with its tuned down 420hp and 15lb boost. Originally it made over 600hp during dyno/ testing program at ~28lb of boost.
The fastest Street 944 16V Turbo has dynoed 625hp with monster torque.
Imagine driving with that everyday!
Later,
