Fully Threaded Bolts or No?

Maybe a silly question, I just don’t want to end up having it bite my butt in the future.

Would it be better to get fully threaded bolts, or just the ones that are threaded on the last inch or so? I’ve seen pictures of both being used, I’m not sure if there’s any mechanical advantage to one versus the other, or if it’s just whatever’s easier to source.

Thanks so much!

Shouldn’t matter much. The strength gains from having a shank on the bolt are totally unnecessary in this case. The shank and major thread diameters should be the same anyways
