What is the difference between the sabres you listed?

Basically the engines.
The original F-86 had the General Electric J-47 engine builtin, except for the F-86H which was equipped with the General Electric J73 including Afterburner.
The Canadair Sabres used the generally more powerful Avro Canada Orenda engine beginning from version Mk.3 on. These are known to be the fastest Sabres around.
The CAC Sabres uses the even more powerful Rolls-Royce Avon R.A.7, which resulted in a re-design of the fuselage as the Avon was shorter, wider and lighter than the General Electric J47, and different armament (2x30mm cannon instead of the M3 guns).
Even though the Avon was the most powerful engine for Sabres (except for the Afterburner equipped F-86H), the CAC versions didn't exceed the other's performance due to the necessary re-design of the fuselage.
