964 C4 vs 993 C2

In the market for a proper old school 911. Found a 964 C4 and a 993 C2. Similar price ($200k aud) and mileage (170k kms). Planning on taking it to a reputed Porsche mechanic for a full restoration so I can keep it running healthy for many years to come. Researching the pros and cons between the two and curious on owners thoughts which they prefer.
