It will be amazing if the Ais version can match the quality of the G version at wide open f1.4. From what I used and read, many old MF lenses can't perform as good as the new G primes at wide open f1.4. But when they stop down f2.0 onwards, the performance will be getting closed.
For the 35 have to ask Kid. Because I did not do the test. But for 50mm or similar range, I like the MF lenses more. Also when u say performance, it is subjective also. Because different people put different weight on different characteristics.
