Zombies die from lack of food or if their bodies eventually rot down. As Titans don't need to eat that would eliminate that disadvantage. As for the body, there would heal although maybe the zombie effect makes it so the healing process takes longer than normal but at a pace where the titan's body never fully rots away and is still fully usable. Let's say their skin isn't as hard as it would be so the scout's swords wouldn't be the only weapon that could cut through it anymore.

As for a positive effect, i would say the effects of zombies being more aggressive at times when hunting for food would make the Titans run faster and react more ruthlessly. I mean most the Titans just walk around slowly and don't really chase after their food a lot of the time so this zombie effect would make all the titans faster in my view and more relentless.

Just imagine a massive zombie colossal Titan then all the wall that's coming out zombified.
