What drives manufacturers to decided between making their clones push pin or clipped?
Kind of new, but it seems Zenith and POF are making push pin guns, and the others are clipped. Is the clipped because adding the shelf is an easier way to make a semi?

I'm no expert, surely they'll be along soon enough, but originally the ATF decided the front pushpin made it too easy to convert to full auto, and required the shelf to be welded on to prevent the FA parts being installed. My understanding is the POF and Zenith firearms have a piece welded in the rear of the receiver that prevents you from using the FA bolt carrier, and I guess the ATF decided that was good enough. Until POF and Zenith came on the scene the semi shelf was the only way it was done. Also, keep in mind the semi shelf was Hk's idea to get around the problem.
Ahh, so the shelf came along only for semi auto.? That would make sense, of why I had to do what I did, to make these packs fit the Zenith. There is no shelf in F/A packs, but the Zenith's have the semi auto shelf AND are push pin guns.
At least with the pin you can buy virtually any style or color of surplus housing and not have any concerns for fitment. There can be better than a $50 difference between a "clipped and pinned" housing, versus a standard untouched surplus. And, granted it doesn't happen all that often, but I've seen several posts of malfunctions here, many contributed to a bad seat of the housing to receiver in a clipped housing.
Of course it has to be said, that if we all weren't concerned with looks as well, we would have bought Hi-Point carbines instead of MP5's.
I knew it was some type of workaround to prevent FA, so it sounds like the shelf/pin & clipped was the original method for that, then Zenith and POF found a different way (I think better), so the below is true.
The PTR 93 rifles from Bud's are clipped/pinned, but hey, for that price.
With the fake pins it isn't too bad I guess, but man, push pins are one of the things that make these guns. I'll never say no, but I don't think I'll ever get one without push pins. It would have to be the deal of the year lol. But that's just me. I won't lie, I got into them half just for their looks. I've wanted what I have for over 30 years lol. You think I wasn't going push pin hahaha
