The "pin in the hole" type are OEM on my Kubota M6040. They work just fine and are a bit quicker than the twist ones that came on my Ford.

Because the spacing of the holes on the inside slider is slightly different from the ones on the outside tube, very small incremental changes can be made to the lower link position by selecting the correct hole for the pin.
I'd think that it would be difficult to find holes in those that would keep the 3ph tight enough to keep it from swinging. With turnbuckles, you can just tighten them up (and you better; broke the 2 on my 4010 one time when I left them too loose).
Biggest problem with turnbuckles might be to lock them in place. I've only ever used tension cords from one side of them us to the tractor body somewhere.

The turnbuckles on my lower arms are lined up and I keep them snug if not my pto winch will slam back and forth on every bump, thats why I was questioning on how to keep implements from doing that on pinned lower arms.You don't really want it very tight. 3 PT is not a perfect linkage setup, quite often the pivot point for the stabilizers is not perfectly aligned with the pivot point for the lift arms. This causes it to bind in certain 3 pt height positions if the turnbuckles are too tight.
On mine with the telescopic style, I get about 1/4" of play and that's exactly how I like to run my 3 pt implements.
