No, the Kodak fixer is a Rapid Hardening fixer not recommended these days, the second is a plain acid fixer very much slower working.

The best fixers are Ilford Rapid fixer or Hypam, very economic no odour, slightly acidic pH 5.2 - 5.4. Kodak make an equivalent.

If you don't like the ammonia smell stay away from neutral/alkaline rapid fixers.
