This is a good question that I'm also curious about.
IIRC I'm using moog manual inners that I bought new. When I picked up my used manual rack it had inners on it already. The overall length was the same between the 2, but there were some differences, pic below:
(The top rod type is unkown, and the bottom is the moog rod.)

I never tried the used tie rods that came with the rack. They were removed and donated to a friend (I'm not sure if he ever tried them).
I ended up installing the rack with the new moog inner tie rods, and also new t3 outer tie rods/knuckles. I also attempted to install t3 rca's but encountered a problem. With the suspension at full droop (full stroke tokico blues, uncut megan springs) there wasn't enough room to fit the rca. The only way I could get room to fit the rca was to jack up the strut without it bolted to the knuckle/control arm (I don't recommend doing this) so there was enough room to fit the rca. The issue with this is the suspension binds at the inner tie rod bushing at full droop with the rca's installed

. Needless to say I'm not running the rca's because of this.
I spoke with Gabe from t3 about this and he had never had this problem, but he also told me he hasn't used moog tie rods. I also haven't heard of anyone else having this problem.
Moral of the story is there
may be small differences between manual and power inner tie rods, and there
may also be differences between manufacturers. In my case I have a feeling the moog tie rods I got have a smaller range of motion, or less articulation than they should have, but that's just speculation on my part.
