I don't know if it's the breed, the breeding line, or just the two individuals we got, because we've only had the two, but they worked all the time. Even when they slept, they weren't always asleep. The Pyrs would work at night, but they couldn't be bothered to work in the daytime. And the Akbashes look UP. Big birds and small Cessnas are not allowed over our airspace.

One of our Pyrs was a "bird dog" like that, but jut one. Conan was the first to start running off the birds when he was only 3 or 4 months old, and Maggie (although she was older than him) learned from him, and now she's just as good as he ever was.
Also, they come back home. They get out of the fence just as bad as the Pyrs ever did, but they don't roam for days (or a WEEK, like our first pair of Pyrs did one time). They stay on the property unless there's a close enough threat, then they go out to take care of it, and come right back. No messing around or wandering, just take care of the business at hand, and get back home.
They also watch over the new calves. The Pyrs never did, or at least I never NOTICED them. They probably were, in a general sort of way, but our Akbash actively stay with the cow and calf for the first couple of weeks, then they leave the immediate area, but if they hear anything (the calf mooing, for example), they'd run right back to check. And usually one of them had calf duty while the other one remained on "General Guard."
Maybe the most important thing of all is, THEY COME WHEN I CALL. That is seriously good. Maggie goes just outside our perimeter fence to the ridge just north of our property, from which she can see and hear for literally miles, every morning early, before the sun comes up. Two of the coyote packs live out that way, so she just goes out to a high spot and warns them to stay away. If she's still out there after it starts getting light, I can call her, and 10 minutes later, here she comes, across the pasture from the far hill, answering my call. NONE of my Pyrs would come when I called like that. None of them. They came back when they were darned good and ready.
It seems like there should be more. The Akbashes are just so much "more" dog, it seems to me. Maggie is my heart dog, for instance. She loves me like nothing else, and the feeling is mutual. She sits in front of me when I'm out in the barn after milking and presses her head against my chest while I'm loving on her, but if she hears one of the guineas make a noise, for example, she's off like a shot to make sure it's OK. I have to be mindful of where my chin is when we're hugging, because she could knock my teeth out with her big ol' Mastiff head when she pops up like that. No amount of petting or distraction from me will keep her from hearing and acting on a perceived threat, and Conan was the same way, but Maggie didn't let him get snuggles from me much. She is a very jealous dog. Conan was mostly Rich's dog (but I loved him just as much as I love Maggie). She's very possessive of me, but she'll drop me like a hot potato if she hears a coyote howl or a hawk scream.
I will never have another breed of LGD if I can help it. I hope Maggie is with me until I don't need one anymore.
Here's a picture of her, one of my favorites. It expresses her personality perfectly.

And this was my boy, Conan:
