Here are my comments about your remarks

1 - "The 20% more hovering altitude" is very vague. Can you tell us what the benchmark value is in determining this increase ? Taken from Wikipedia, this reference is not very clear.
2 - AH-64 units have been operating in Afghanistan, which has a geography very much like SE Turkey, if not more rugged, with a high degree of success and user satisfaction. You can check Apache unit performances and effectiveness in Operation Enduring Freedom on open sources. The AH-64 has proven itself to be a platform with exceptional CAS ability, and survivability.
3 - The initial ATAK project was cancelled due to a multitude of restraints. First and foremost was budget concerns. Secondly, although Turkish Armed Forces preferred AH-1 or AH-64 over any other platforms, due to problems in technology transfer, software codes and Offset obligations, the first ATAK project was cancelled. Let us remember here that AH-1 Super Cobra was the winner.

T-129 is a second/third choice for the Turkish Armed Forces. This is a story similar to T-155 Firtina which had to be co-developed with S.Korea after German denial for the transfer of certain subsystems for a PzH2000 based system to be developed.

Turkish Armed Forces asked for greater firepower, proven technology and ownership of all licences in both cases. When these were refused, they had to make to with second or third choices.

I do not think it is fruitful to compare a light/medium attack helicopter like the T-129 with AH-64, which itself is a benchmark among attack helicopter platforms. Let us see the T-129 fly first. I hope it does not end up like the Eryx project...
